Sushi

About sushi
Sushi (寿司, 鮨, or 鮓) is cooked vinegar rice that is commonly topped with fish which can be cooked or raw. Sliced raw fish alone is called sashimi, as distinct from. When sushi is combined with another word such as 'chirashi' or 'nigiri', the 's' turns into a z, forming chirashi-zushi and nigiri-zushi. Sushi that is served rolled inside or around dried and pressed layer sheets of seaweed is called nigiri-zushu. Toppings stuffed into a small pouch of fried tofu is called inari-zushi. Toppings served scattered over a bowl of sushi rice is called chirashi-zushi (ちらし).

Types of sushi
The common ingredient across all the different kinds of sushi is short-grain rice. The variety in sushi arises from the different fillings and toppings, condiments, and the way these ingredients are put together. The same ingredients may be assembled in a traditional or a contemporary way, creating a very different final result. 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.

Nigiri-zushi
Nigirizushi (握り寿司, lit. hand-formed sushi) consists of an oblong mound of rice that is pressed between the palms of the hands and a topping draped over it. Toppings 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 rolled egg (tamago). When ordered separately, nigiri is generally served in pairs. A sushi set may contain only one piece of each topping.


 * Gunkanmaki (軍艦巻, lit. warship roll) is a special type of nigirizushi: an oval, hand-formed clump of rice that has a strip of "nori" wrapped around its perimeter to form a vessel that is filled with some hard, loose or ruffly chopped ingredient that requires the confinement of nori such as roe, natto, oysters, sea urchin, corn with mayonnaise, and quail eggs. Gunkan-maki was invented at the Ginza Kyubey restaurant in 1931; its invention significantly expanded the repertoire of soft toppings used in sushi.


 * Temarizushi (手まり寿司, lit. ball sushi) is a ball-shaped sushi made by pressing rice and fish into a ball-shape form by hand. They are quite easy to make and thus a good starting point for beginners.

Makizushi
Makizushi (巻寿司, lit. rolled sushi) or makimono (巻物, lit. variety of rolls) is cylindrical piece, formed with the help of a bamboo mat, called a makisu (巻簾). Makizushi is generally wrapped in nori, but can occasionally be found wrapped in a thin omelette, soy paper, cucumber, or parsley. 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, lit. thick, large or fat rolls) is a large cylindrical piece, with nori on the outside. A typical futomaki is three or four centimeters (1.5 in) in diameter. They are often made with two or three fillings that are chosen for their complementary tastes and colors. During the Setsubun festival, it is traditional in Kansai to eat uncut futomaki in its cylindrical form, where it is particularly called ehou-maki (恵方巻, lit. happy direction rolls). Futomaki is often vegetarian, but may include non-vegetarian toppings such as tiny fish roe and chopped tuna.


 * Hosomaki (細巻, lit. small rolls) is a small cylindrical piece, with the nori on the outside. A typical hosomaki has a diameter of about two centimeters (0.75 in). 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 some believe that the name "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. Negitoromaki (ねぎとろ巻) is a kind of Hosomaki filled with scallion and chopped tuna. 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.


 * Temaki (手巻, lit. hand rolls) 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 and becomes somewhat difficult to bite.


 * Uramaki (裏巻, lit. inside-out rolls) is a medium-sized cylindrical piece, with two or more fillings. 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 an outer coating of some other ingredients such as roe or toasted sesame seeds. A common example in the United States would be the California roll. Uranaki can be made with different fillings such as tuna, crab meat, avocado, mayonnaise, cucumber, carrots. Uramaki has not been so popular in Japan because it is easier to hold makimono with nori skin by fingers. However, since some Western people dislike the black impression of makimono with nori skin, uramaki has become more popular in Western countries than nori-skined makimono.

Oshizushi
Oshizushi (押し寿司, lit. pressed sushi), is a pressed sushi from the Kansai Region, a favourite and specialty of Osaka. A block-shaped piece 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.

Inarizushi
Inarizushi (稲荷寿司, stuffed sushi) is a pouch of fried tofu filled with usually just sushi rice. 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 very large version, sweeter than normal and often containing bits of carrot, is popular in Hawaii, where it is called "cone sushi."

Sukeroku
Sukeroku (助六, name of a man in Edo period) is the combination set of inarizushi and makizushi, which is served as a single-portion takeout style sushi-pack. In a famous Kabuki play Sukeroku, a good-looking man Sukeroku is the lover of an Oiran courtesan named Agemaki (揚巻, lit. fry for age and roll for maki). Age and maki which form her name correspond to fried tofu namely inari and makimono, respectively. One rumour of sukeroku-zushi is that takeout style packs of inarizushi and makizushi had served at performances of Sukeroku kabuki in Edo period. Sukeroku is a cheap sushi-pack and often vegetarian.

Chirashizushi
Chirashizushi (ちらし寿司, lit. scattered sushi) is a bowl of sushi rice with other ingredients mixed in (also refers to barazushi). It is commonly eaten in Japan because it is filling, fast and easy to make. Chirashizushi most often varies regionally because it is eaten annually as a part of the Doll Festival, celebrated only during March in Japan. The ingredients are often chef's choice. Edomae chirashizushi (Edo-style scattered sushi) is an uncooked ingredient that is arranged artfully on top of the sushi rice in a bowl. Gomokuzushi (Kansai-style sushi) are cooked or uncooked ingredients mixed in the body of rice in a bowl.

Narezushi
Narezushi (熟れ寿司, lit. 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 funazushi can be eaten, remaining edible for another six months or more.

Western-style sushi
The increasing popularity of sushi in North America as well as around the world has resulted in variations of sushi typically found in the West but rarely if at all in Japan. Such creations to suit the Western palate were initially fueled by the invention of the California roll. A wide variety of popular rolls has evolved since.
