Sushi (すし, 寿司, 鮨) is a type of food preparation originating in Japan, consisting of cooked vinegared rice (鮨飯 sushi-meshi) combined with other ingredients (ネタ neta) such as seafood, meat, vegetables and sometimes tropical fruits. Ingredients and forms of sushi presentation vary widely, but the ingredient which all sushi have in common is rice (also referred to as shari (しゃり) or sumeshi (酢飯)). Although commonly mistaken for sushi, sashimi, which is also a Japanese delicacy, consists of thinly sliced raw meat or fish and may or may not be served with rice.

Sushi can be prepared with either brown or white rice. It is often prepared with raw seafood, but some common varieties of sushi use cooked ingredients and many are vegetarian. Sushi is often served with pickled ginger, wasabi, and soy sauce. Popular garnishes are often made using daikon.

History

Main article: History of sushi
Sushi by Hiroshige in Edo period

The original type of sushi, known today as nare-zushi (馴れ寿司, 熟寿司,) was first made in Southeast Asia. Fish was salted and wrapped in fermented rice, a traditional lacto-fermented rice dish. Narezushi was made of this gutted fish which was stored in fermented rice for months at a time for preservation. The fermentation of the rice prevented the fish from spoiling.[1] The fermented rice was discarded and fish was the only part consumed. This early type of sushi became an important source of protein for the Japanese. The term sushi comes from an antiquated grammatical form no longer used in other contexts, and literally means "sour-tasting", a reflection of its historic origin as a fermented food. The oldest form of sushi in Japan, narezushi, is still made by wrapping fish in soured fermenting rice, which causes the fish proteins to break down into their constituent amino acids. The fermenting rice and fish have both a sour and an umami taste.[2]

Contemporary Japanese sushi has little resemblance to the traditional lacto-fermented rice dish. Originally, when the fermented fish was taken out of the rice, only the fish was consumed while the fermented rice was discarded.[3] The strong-tasting and smelling funazushi, a kind of narezushi made near Lake Biwa in Japan, resembles the traditional fermented dish. Beginning in the Muromachi period (1336–1573) of Japan, vinegar was added to the mixture for better taste and preservation. The vinegar accentuated the rice's sourness and was known to increase its shelf life, allowing the fermentation process to be shortened and eventually abandoned. In the following centuries, sushi in Osaka evolved into oshi-zushi. The seafood and rice were pressed using wooden (usually bamboo) molds. By the mid 18th century, this form of sushi had reached Edo (contemporary Tokyo).[4]

The contemporary version, internationally known as "sushi", was created by Hanaya Yohei (1799–1858) at the end of the Edo period in Edo. Sushi invented by Hanaya was an early form of fast food that was not fermented (therefore prepared quickly) and could be conveniently eaten with one's hands. The size of the previous sushi was about three times as large as contemporary ones.[4] Originally, this sushi was known as Edomae zushi because it used freshly caught fish in the Edo-mae (Edo Bay or Tokyo Bay). Though the fish used in modern sushi no longer usually comes from Tokyo Bay, it is still formally known as Edomae nigirizushi.[5][6]

The Oxford English Dictionary notes the earliest written mention of sushi in English in an 1893 book, A Japanese Interior, where it mentions sushi as "a roll of cold rice with fish, sea-weed, or some other flavoring".[7][8] However, there is also mention of sushi in a Japanese-English dictionary from 1873,[9] and an 1879 article on Japanese cookery in the journal Notes and Queries.[10]

Types

Types of sushi. Clockwise from top-left: nigirizushi, makizushi, temaki.

The common ingredient across all kinds of sushi is vinegared sushi rice. Variety arises from fillings, toppings, condiments, and preparation. Traditional versus contemporary methods of assembly may create very different results from very similar ingredients.[11] In spelling sushi, its first letter s is replaced with z when a prefix is attached, as in nigirizushi, due to consonant mutation called rendaku in Japanese.

Chirashizushi

Chirashizushi with raw ingredients

Chirashizushi (ちらし寿司, "scattered sushi") is a bowl of sushi rice topped with a variety of raw fish and vegetables/garnishes (also refers to barazushi). There is no set formula for the ingredients; they are either chef's choice or specified by the customer. It is commonly eaten because it is filling, fast and easy to make. Chirashizushi also often varies regionally. It is eaten annually on Hinamatsuri in March.

Inarizushi

Inarizushi
Wikibooks Cookbook has a recipe/module on

Inarizushi (稲荷寿司) is a pouch of fried tofu typically filled with sushi rice alone. It is named after the Shinto god Inari, who is believed to have a fondness for fried tofu. The pouch is normally fashioned as deep-fried tofu (油揚げ, abura age). Regional variations include pouches made of a thin omelette (帛紗寿司, fukusa-zushi, or 茶巾寿司, chakin-zushi). It should not be confused with inari maki, which is a roll filled with flavored fried tofu.

A version of inarizushi that includes green beans, carrots, and gobo along with rice, wrapped in a triangular aburage (fried tofu) piece, is a Hawaiian specialty, where it is called cone sushi and is often sold in okazu-ya (Japanese delis) and as a component of bento boxes.[12][13][14][15]

Makizushi

Futomaki
Makizushi in preparation

Makizushi (巻き寿司, "rolled sushi"), norimaki (海苔巻き, "Nori roll") or makimono (巻物, "variety of rolls") is a cylindrical piece, formed with the help of a bamboo mat known as a makisu (巻簾). Makizushi is generally wrapped in nori (seaweed), but is occasionally wrapped in a thin omelette, soy paper, cucumber, or shiso (perilla) leaves. Makizushi is usually cut into six or eight pieces, which constitutes a single roll order. Below are some common types of makizushi, but many other kinds exist.

Futomaki (太巻, "thick, large or fat rolls") is a large cylindrical piece, usually with nori on the outside.[16] A typical futomaki is five to six centimeters (2–2.5 in) in diameter.[17] They are often made with two, three, or more fillings that are chosen for their complementary tastes and colors. During the evening of the Setsubun festival, it is traditional in the Kansai region to eat uncut futomaki in its cylindrical form, where it is called ehō-maki (恵方巻, lit. happy direction rolls).[18] By 2000 the custom had spread to all of Japan.[19] Futomaki are often vegetarian, and may utilize strips of cucumber, kampyō gourd, takenoko bamboo shoots, or lotus root. Strips of tamagoyaki omelette, tiny fish roe, chopped tuna, and oboro whitefish flakes are typical non-vegetarian fillings.[16] Traditionally, the rice is lightly seasoned with salt and sesame oil/perilla oil. Popular protein ingredients are fish cakes, imitation crab meat, eggs and/or seasoned beef rib-eye. Vegetables usually include cucumbers, spinach, carrot and takuan (沢庵) (pickled radish). After the makizushi has been rolled and sliced, it is typically served with takuan.

Short grain white rice is usually used, although short-grain brown rice, like olive oil on nori, is now becoming more widespread among the health-conscious. Rarely, sweet rice is mixed in makizushi rice. Nowadays, the rice in makizushi can be many kinds of black rice, boiled rice and cereals etc.Besides the common ingredients listed above, some varieties may include cheese, spicy cooked squid, yakiniku, kamaboko, lunch meat, or spicy tuna. The nori may be brushed with sesame oil or sprinkled with sesame seeds. In a variation, sliced pieces of makizushi may be lightly fried with egg coating.

Hosomaki (細巻, "thin rolls") is a small cylindrical piece, with nori on the outside. A typical hosomaki has a diameter of about two and a half centimeters (1 in).[17] They generally contain only one filling, often tuna, cucumber, kanpyō, thinly sliced carrots, or, more recently, avocado. Kappamaki, (河童巻) a kind of Hosomaki filled with cucumber, is named after the Japanese legendary water imp fond of cucumbers called the kappa. Traditionally, kappamaki is consumed to clear the palate between eating raw fish and other kinds of food, so that the flavors of the fish are distinct from the tastes of other foods. Tekkamaki (鉄火巻) is a kind of hosomaki filled with raw tuna. Although it is believed that the word tekka, meaning "red hot iron", alludes to the color of the tuna flesh or salmon flesh, it actually originated as a quick snack to eat in gambling dens called tekkaba (鉄火場), much like the sandwich.[20][21] Negitoromaki (ねぎとろ巻) is a kind of hosomaki filled with scallion (negi) and chopped tuna (toro). Fatty tuna is often used in this style. Tsunamayomaki (ツナマヨ巻) is a kind of hosomaki filled with canned tuna tossed with mayonnaise.

Ehōmaki with a setsubun mask.

Ehōmaki (恵方巻, "lucky direction roll") is a roll composed of seven ingredients considered to be lucky. Ehōmaki are often eaten on setsubun in Japan. The typical ingredients include kanpyō, egg, eel, and shiitake mushrooms. Ehōmaki often include other ingredients too. People usually eat the ehōmaki while facing the direction considered to be auspicious that year.[22]

Temaki (手巻, "hand roll") is a large cone-shaped piece of nori on the outside and the ingredients spilling out the wide end. A typical temaki is about ten centimeters (4 in) long, and is eaten with fingers because it is too awkward to pick it up with chopsticks. For optimal taste and texture, temaki must be eaten quickly after being made because the nori cone soon absorbs moisture from the filling and loses its crispness, making it somewhat difficult to bite through. For this reason, the nori in pre-made or take-out temaki is sealed in plastic film which is removed immediately before eating.[23]

Narezushi

funa-zushi (narezushi made from a crucian carp species)

Narezushi (熟れ寿司, "matured sushi") is a traditional form of fermented sushi. Skinned and gutted fish are stuffed with salt, placed in a wooden barrel, doused with salt again, then weighed down with a heavy tsukemonoishi (pickling stone). As days pass, water seeps out and is removed. After six months, this sushi can be eaten, remaining edible for another six months or more.[24] The most famous variety of narezushi still being produced is funa-zushi (made from fish of the crucian carp genus, authentically from C. auratus grandoculis (nigoro-buna) endemic to Lake Biwa), a typical dish of Shiga Prefecture.

Nigirizushi

Sea urchin roe "gunkanmaki"

Nigirizushi (握り寿司, "hand-pressed sushi") consists of an oblong mound of sushi rice that the chef presses between the palms of the hands to form an oval-shaped ball, and a topping (the neta) draped over the ball. It is usually served with a bit of wasabi; neta are typically fish such as salmon, tuna or other seafood. Certain toppings are typically bound to the rice with a thin strip of nori, most commonly octopus (tako), freshwater eel (unagi), sea eel (anago), squid (ika), and sweet egg (tamago). One order of a given type of fish typically results in two pieces, while a sushi set (sampler dish) may contain only one piece of each topping.

Gunkanmaki (軍艦巻, "warship roll") is a special type of nigirizushi: an oval, hand-formed clump of sushi rice that has a strip of nori wrapped around its perimeter to form a vessel that is filled with some soft, loose or fine-chopped ingredient that requires the confinement of nori such as roe, nattō, oysters, uni (sea urchin roe), corn with mayonnaise, scallops, and quail eggs. Gunkan-maki was invented at the Ginza Kyubey restaurant in 1941; its invention significantly expanded the repertoire of soft toppings used in sushi.[25][26]

Temarizushi (手まり寿司, "ball sushi") is a sushi made by pressing rice and fish into a ball-shaped form by hand using a plastic wrap.[27]

Oshizushi

Sasazushi, a type of oshizushi

Oshizushi (押し寿司, "pressed sushi"), also known as 箱寿司, hako-zushi, "box sushi"), is a pressed sushi from the Kansai region, a favorite and specialty of Osaka. A block-shaped piece is formed using a wooden mold, called an oshibako. The chef lines the bottom of the oshibako with the toppings, covers them with sushi rice, and then presses the lid of the mold down to create a compact, rectilinear block. The block is removed from the mold and then cut into bite-sized pieces. Particularly famous is バッテラ (battera, pressed mackerel sushi) or 鯖寿司 (saba zushi).[28] In oshizushi, all the ingredients are either cooked or cured and raw fish is never used.[29]

Western-style sushi

Norway roll (ノルウェー巻き). Bjorn Eirik Olsen, a Norwegian businessman, introduced the use of salmon as a sushi ingredient to Japanese in the 1980s.[30]

The increasing popularity of sushi around the world has resulted in variations typically found in the Western world, but rarely in Japan (a notable exception to this is the use of salmon, which was introduced by Bjorn Eirik Olsen, a Norwegian businessman tasked with helping the Norwegian salmon industry sell more fish in the early 1980s[31][32]). Such creations to suit the Western palate were initially fueled by the invention of the California roll (a norimaki with crab (later, imitation crab), cucumber, and avocado). A wide variety of popular rolls (norimaki and uramaki) has evolved since. Norway roll is another variant of uramakizushi filled with tamago (omelette), imitation crab and cucumber, rolled with shiso leaf and nori, topped with slices of Norwegian salmon, garnished with lemon and mayonnaise.[33]

Uramaki

Uramakizushi rolls

Uramaki (裏巻, "inside-out roll") is a medium-sized cylindrical piece with two or more fillings, and was innovated as a result of the creation of the California roll, as a method originally meant to hide the nori. Uramaki differs from other makimono because the rice is on the outside and the nori inside. The filling is in the center surrounded by nori, then a layer of rice, and optionally an outer coating of some other ingredients such as roe or toasted sesame seeds. It can be made with different fillings, such as tuna, crab meat, avocado, mayonnaise, cucumber or carrots.

Examples of variations include the rainbow roll (an inside-out topped with thinly sliced maguro, hamachi, ebi, sake and avocado) and the caterpillar roll (an inside-out topped with thinly sliced avocado). Also commonly found is the "rock and roll" (an inside-out roll with barbecued freshwater eel and avocado with toasted sesame seeds on the outside).

In Japan, uramaki is an uncommon type of makimono; because sushi is traditionally eaten by hand in Japan, the outer layer of rice can be quite difficult to handle with fingers.[34]

American-style makizushi

Futomaki is a more popular variation of sushi within the United States, and comes in variations that take their names from their place of origin. Other rolls may include a variety of ingredients, including chopped scallops, spicy tuna, beef or chicken teriyaki roll, okra, and assorted vegetables such as cucumber and avocado, and the "tempura roll", where shrimp tempura is inside the roll or the entire roll is battered and fried tempura-style. In the Southern United States, many sushi restaurants prepare rolls using crawfish. Sometimes, rolls are made with brown rice or black rice, which appear in Japanese cuisine as well.

Per Food and Drug Administration regulations, raw fish served in the United States must be frozen prior to serving in order to kill parasites.[35] Because of this and the relative difficulty of acquiring fresh seafood compared to Japan, raw seafood (e.g., sashimi) is not as prevalent of a component in American-style sushi.

Since rolls are usually made to-order it is not unusual for the customer to specify the exact ingredients desired (e.g. salmon roll, cucumber roll, avocado roll, Shrimp/tuna tempura roll, tuna roll, etc.). Though the menu names of dishes often vary by restaurant, some examples include:

Sushi roll name Definition
Alaska(n) roll a variant of the California roll with raw salmon on the inside, or layered on the outside.[36]
Boston roll An uramaki California roll with poached shrimp instead of imitation crab.[37]
British Columbia roll contains grilled or barbecued salmon skin, cucumber, sweet sauce, sometimes with roe. Also sometimes referred to as salmon skin rolls outside of British Columbia, Canada.[38]

Dynamite roll includes yellowtail (hamachi) and/or prawn tempura, and fillings such as bean sprouts, carrots, avocado, cucumber, chili, spicy mayonnaise, and roe.[40]
Hawaiian roll contains shoyu tuna (canned), tamago, kanpyō, kamaboko, and the distinctive red and green hana ebi (shrimp powder).[41]
Mango roll includes fillings such as avocado, crab meat, tempura shrimp, mango slices, and topped off with a creamy mango paste.[42]
Michigan roll includes fillings such as spicy tuna, smelt roe, spicy sauce, avocado, and sushi rice. Is a variation on spicy tuna roll.[43]
New Mexico roll originating in New Mexico; includes New Mexico green chile (sometimes tempura fried), teriyaki sauce, and rice.[44][45] Sometimes simply referred to as a "green chile (tempura) roll" within the state.[46][47]

Ingredients

All sushi has a base of specially prepared rice, complemented with other ingredients.

Sushi-meshi

Sushi-meshi 鮨飯 (also known as Su-meshi 酢飯, shari 舎利, or gohan ご飯) is a preparation of white, short-grained, Japanese rice mixed with a dressing consisting of rice vinegar, sugar, salt, and occasionally kombu and sake. It has to be cooled to room temperature before being used for a filling in a sushi or else it will get too sticky while being seasoned. Traditionally, the mixing is done with a hangiri, which is a round, flat-bottom wooden tub or barrel, and a wooden paddle (shamoji).

Sushi rice is prepared with short-grain Japanese rice, which has a consistency that differs from long-grain strains such as those from India, Sri Lanka, Bangladesh, Thailand, and Vietnam. The essential quality is its stickiness or glutinousness, although the type of rice used for sushi is different from glutinous rice. Freshly harvested rice (shinmai) typically contains too much water, and requires extra time to drain the rice cooker after washing. In some fusion cuisine restaurants, short-grain brown rice and wild rice are also used.

There are regional variations in sushi rice and, of course, individual chefs have their individual methods. Most of the variations are in the rice vinegar dressing: the Kantō region (or East Japan) version of the dressing commonly uses more salt; in Kansai region (or West Japan), the dressing has more sugar.

Nori

Sheets of nori.
Main article: Nori

The black seaweed wrappers used in makimono are called nori. Nori is a type of algae, traditionally cultivated in the harbors of Japan. Originally, algae was scraped from dock pilings, rolled out into thin, edible sheets, and dried in the sun, in a process similar to making rice paper. Today, the commercial product is farmed, processed, toasted, packaged, and sold in sheets.

The size of a nori sheet influences the size of makimono. A full-size sheet produces futomaki, and a half produces hosomaki and temaki. To produce gunkan and some other makimono, an appropriately-sized piece of nori is cut from a whole sheet.

Nori by itself is an edible snack and is available with salt or flavored with teriyaki sauce. The flavored variety, however, tends to be of lesser quality and is not suitable for sushi.

When making fukusazushi, a paper-thin omelette may replace a sheet of nori as the wrapping. The omelette is traditionally made on a rectangular omelette pan (makiyakinabe), and used to form the pouch for the rice and fillings.

Neta

Sushi made of meats other than fish (whether raw or cooked) is a variation often seen in Japan.
Yaki anago-ippon-nigiri (焼きアナゴ一本握り) – a roasted and sweet-sauced whole conger
Ebifurai-maki (エビフライ巻き) – fried-shrimp roll
Date-Maki (伊達巻) futomaki wrapped with sweet tamagoyaki

For culinary, sanitary, and aesthetic reasons, the minimum quality and freshness of fish to be eaten raw must be superior to that of fish which is to be cooked. Sushi chefs are trained to recognize important attributes, including smell, color, firmness, and freedom from parasites that may go undetected in commercial inspection. Commonly used fish are tuna (maguro, shiro-maguro), Japanese amberjack, yellowtail (hamachi), snapper (kurodai), mackerel (saba), and salmon (sake). The most valued sushi ingredient is toro, the fatty cut of the fish. This comes in a variety of ōtoro (often from the bluefin species of tuna) and chūtoro, meaning "middle toro", implying that it is halfway into the fattiness between toro and the regular cut. Aburi style refers to nigiri sushi where the fish is partially grilled (topside) and partially raw. Most nigiri sushi will have completely raw neta.

Other seafoods such as squid (ika), eel (anago and unagi), pike conger (hamo), octopus (tako), shrimp (ebi and amaebi), clam (mirugai, aoyagi and akagai), fish roe (ikura, masago, kazunoko and tobiko), sea urchin (uni), crab (kani), and various kinds of shellfish (abalone, prawn, scallop) are the most popular seafoods in sushi. Oysters, however, are less common, as the taste is not thought to go well with the rice. Kani kama, or imitation crab stick, is commonly substituted for real crab, most notably in California rolls.

Pickled daikon radish (takuan) in shinko maki, pickled vegetables (tsukemono), fermented soybeans (nattō) in nattō maki, avocado, cucumber in kappa maki, asparagus, yam, pickled ume (umeboshi), gourd (kanpyō), burdock (gobo), and sweet corn (possibly mixed with mayonnaise) are also used in sushi.

Tofu and eggs (in the form of slightly sweet, layered omelette called tamagoyaki and raw quail eggs ride as a gunkan-maki topping) are common.

Condiments

Sushi is commonly eaten with condiments. Sushi may be dipped in shōyu, soy sauce, and is usually flavored with wasabi, a piquant paste made from the grated root of the Wasabia japonica plant. Japanese-style mayonnaise is a common condiment in Japan on salmon, pork and other sushi cuts.

True wasabi has anti-microbial properties and may reduce the risk of food poisoning.[52] The traditional grating tool for wasabi is a sharkskin grater or samegawa oroshi. An imitation wasabi (seiyo-wasabi), made from horseradish, mustard powder and green dye is common. It is found at lower-end kaiten-zushi restaurants, in bento box sushi and at most restaurants outside Japan. If manufactured in Japan, it may be labelled "Japanese Horseradish".[53]

Gari (sweet, pickled ginger) is eaten in between sushi courses to both cleanse the palate and aid in digestion. In Japan, green tea (ocha) is invariably served together with sushi. Better sushi restaurants often use a distinctive premium tea known as mecha. In sushi vocabulary, green tea is known as agari.

Sushi may be garnished with gobo, grated daikon, thinly sliced vegetables, carrots/radishes/cucumbers that have been shaped to look like flowers, real flowers and/or seaweed salad.

When closely arranged on a tray, different pieces are often separated by green strips called baran or kiri-zasa (切り笹). These dividers prevent the flavors of neighboring pieces of sushi from mixing and help to achieve an attractive presentation. Originally, these were cut leaves from the Aspidistra elatior (葉蘭 haran) and Sasa veitchii (熊笹 kuma-zasa) plants, respectively. Using actual leaves had the added benefit of releasing antimicrobial phytoncides when cut thereby extending the limited shelf life of the sushi.[54] Sushi bento boxes are a staple of Japanese supermarkets and convenience stores. As these stores began rising in prominence in the 1960s, the labor-intensive cut leaves were increasingly replaced with green plastic in order to lower costs. This coincided with the increased prevalence of refrigeration which acted to extend the shelf life of sushi without the need for the cut leaves. Today the plastic strips are commonly used in sushi bento boxes and to a lesser degree in sushi presentations found in sushi bars and restaurants. In store-sold or to-go packages of sushi, the plastic leaf strips are often used to prevent the rolls from coming into early or unwanted contact with the ginger and wasabi included with the dish.[55]

Nutrition

Sushi in shops are usually sold in plastic trays.

The main ingredients of traditional Japanese sushi, raw fish and rice, are naturally low in fat, high in protein, carbohydrates (the rice only), vitamins, and minerals, as are gari and nori. Other vegetables wrapped within the sushi also offer various vitamins and minerals. Many of the seafood ingredients also contain omega-3 fatty acids, which have a variety of health benefits.

Health risks

Some of the ingredients in sushi can present health risks. Large marine apex predators such as tuna (especially bluefin) can harbor high levels of methylmercury, which can lead to mercury poisoning when consumed in large quantity[56] or when consumed by certain higher-risk groups, including women who are pregnant or may become pregnant, nursing mothers and young children.[57]

According to recent studies, there have been about 18 million infections worldwide from eating raw fish.[58] This serves as a great risk to expecting mothers due to the health risks that medical interventions or treatment measures may pose on the developing fetus.[58] Parasitic infections can have a wide range of health impacts, including bowel obstruction, anemia, liver disease, and more.[58] The impact of these illnesses alone can pose some health concerns on the expecting mother and baby, but the curative measures that may need to take place to recover are also of concern as well.[58]

Sashimi or other types of sushi containing raw fish present a risk of infection by three main types of parasites:

For the above reasons, EU regulations forbid the use of fresh raw fish. It must be frozen at temperatures below −20 °C (−4 °F) in all parts of the product for no less than 24 hours.[62] As such, a number of fishing boats, suppliers and end users "super-freeze" fish for sushi to temperatures as low as −60 °C.[63] As well as parasite destruction, super-freezing also prevents oxidation of the blood in tuna flesh, thus preventing the discoloration that happens at temperatures above −20 °C.[64]

Some forms of sushi, notably those containing pufferfish fugu and some kinds of shellfish, can cause severe poisoning if not prepared properly. Particularly, fugu consumption can be fatal. Fugu fish has a lethal dose of tetrodotoxin in its internal organs and, by law in many countries, must be prepared by a licensed fugu chef who has passed the prefectural examination in Japan.[65] The licensing examination process consists of a written test, a fish-identification test, and a practical test, preparing and eating the fish. Only about 35 percent of the applicants pass.[66]

Sustainable sushi

Main article: Sustainable sushi

Sustainable sushi is sushi made from fished or farmed sources that can be maintained or whose future production does not significantly jeopardize the ecosystems from which it is acquired. Concerns over the sustainability of sushi ingredients arise from greater concerns over environmental, economic and social stability and human health.

Presentation

Sushi served on a wooden platter at a sushi restaurant in Kanagawa Prefecture (神奈川県), Japan.

Traditionally, sushi is served on minimalist Japanese-style, geometric, mono- or duo-tone wood or lacquer plates, in keeping with the aesthetic qualities of this cuisine.

Many sushi restaurants offer fixed-price sets, selected by the chef from the catch of the day. These are often graded as shō-chiku-bai (松竹梅), shō/matsu (, pine), chiku/take (, bamboo) and (bai/ume), with matsu the most expensive and ume the cheapest. Sushi restaurants will often have private booth dining, where guests are asked to remove their shoes, leaving them outside the room; However, most sushi bars offer diners a casual experience with an open dining room concept.

Sushi may be served kaiten zushi (sushi train) style. Color-coded plates of sushi are placed on a conveyor belt; as the belt passes, customers choose as they please. After finishing, the bill is tallied by counting how many plates of each color have been taken. Newer kaiten zushi restaurants use barcodes or RFID tags embedded in the dishes to manage elapsed time after the item was prepared.

Glossary

Some specialized or slang terms are used in the sushi culture. Most of these terms are used only in sushi bars.

Etiquette

Unlike sashimi, which is almost always eaten with chopsticks, nigirizushi is traditionally eaten with the fingers, even in formal settings.[69] Although it is commonly served on a small platter with a side dish for dipping, sushi can also be served in a bento, a box with small compartments that hold the various dishes of the meal.

Soy sauce is the usual condiment, and sushi is normally served with a small sauce dish, or a compartment in the bento. Traditional etiquette suggests that the sushi is turned over so that only the topping is dipped; this is because the soy sauce is for flavoring the topping, not the rice, and because the rice would absorb too much soy sauce and would fall apart.[70] If it is difficult to turn the sushi upside-down, one can baste the sushi in soy sauce using gari (sliced ginger) as a brush. Toppings that have their own sauce (such as eel) should not be eaten with soy sauce.

Traditionally, the sushi chef will add an appropriate amount of wasabi to the sushi while preparing it, and etiquette suggests eating the sushi as is, since the chef is supposed to know the proper amount of wasabi to use. However, today wasabi is more a matter of personal taste, and even restaurants in Japan may serve wasabi on the side for customers to use at their discretion, even when there is wasabi already in the dish.[71]

Now the expression Edomae-zushi is employed as a synonym for high quality nigiri-zushi.
