NAMA
A prefix which means raw. (The same prefix applied to beer, nama-biiru, means draught.)

 

NAMA-TAKO
Fresh or raw octopus. Most octopus served in sushi restaurants in the U.S. is frozen. Since it is too chewy to be eaten raw, it is lightly cooked.

 

NANAMI TOGARASHI
A table spice made of seven ingredients: black hemp seeds or white poppy seeds, dried mandarin orange peel, ground sansho pepper pods (which provide heat), nori seaweed bits, red pepper (togarashi) and white sesame seeds. You can buy it at Asian grocers or online.

NARE-ZUSHI or NAREZUSHI
The earliest form of sushi, known today as nare-zushi (“fermented sushi”), was developed in Southeast Asia before the common era (B.C.E.). It was a preservation technique that enabled storage of fish, an important source of protein. Salted fish was packed with fermented rice in alternating layers in a wood box. This preserved the fish for six months to a year [source]. The lacto-fermentation of the rice prevented the fish from spoiling. The rice, which was by then inedible, would be discarded before serving the fish. The fish had a sour and umami flavor profile, and is still made in Japan.

This type of pressed sushi was reserved for the wealthy due to the time and labor involved in preparation.

 

The technique spread to south China, and arrived in Japan in the early 8th century C.E. (source). Vinegar began to be added to the preparation during the Muromachi period (1336–1573), the period of shogun rulers. By the 1600s, pressed sushi in vinegared rice enabled the rice to be eaten, rather than discarded. This practice reached Edo (modern Tokyo) by the 18th century.

 

The vinegar both shortened the fermentation process and enhanced the flavor of the fish. Each region of Japan developed its own style, based on local fish and climate. Over centuries in Osaka, it evolved into oshi-zushi: fish pressed with vinegared rice into wooden molds (square, rectangular, round), then sliced and served.

 

It was in Edo that contemporary sushi was created by Hanaya Yohei (1799–1858), at the end of Edo period (which spanned 1603 to 1868). He bypassed all fermentation  to prepare sushi very quickly, on a hand-molded pad of rice with a swipe of wasabi. It was shaped for conveniently eating as finger food. This street food sold in stands in marketplaces and other gathering spots. The niceties of chopsticks came when sushi became restaurant food (Yohei opened his own resto). The style, originally called edomae zushi: edo for the city and mae* for the freshly caught fish from Tokyo Bay.

After the Great Kanto Earthquake leveled Tokyo in 1923, its sushi chefs spread throughout the country and set up establishments. Sushi was no longer street food, but a special restaurant meal.

_____

*Mae means “front,” and “caught in the front” refers to caught in Tokyo Bay.

 

NASU
Eggplant.

 

 

 

NATTO

Natto is boiled, fermented soybeans. It is a traditional food usually consumed along with miso soup, fish and rice. The soybeans are used in sushi rolls, gunkan maki and inari sushi pockets, shown in the photo, where it is mixed with scallions. (Get the recipe from ShizuokaGourmet.com.)

 

Natto has a very strong taste and aroma that is a challenge for some Westerners to appreciate. However, as a fermented food, it is rich in macronutrients and micronutrients.

NARUTO
A roll (maki) wrapped in cucumber instead of nori seaweed. See the photo at right.

 

NEGI

Scallion or green onion. It is typically minced for sushi and sashimi.

 

NEGI-TORO
Chopped toro and scallion, a popular mixture for rolls and hand rolls. Given the price and delicacy of toro, however, it’s better to eat it as sashimi or sushi without the scallions. Most sushi bars in the U.S. serve negi-maguro, the dark red tuna called tekkamaki when in a roll. The word tekka means hot iron, alluding to the color of maguro (photo at right).

NETA
Neta refers to sushi made with varied ingredients: seafood, vegetables and sometimes, fruits.

 

NIGIRI-SUSHI
A pad or “finger” of vinegared rice upon which a slice of fish or other topping is layered. This style was developed in Tokyo, then known as Edo, at the beginning of the 19th century, and was served at food stalls. It is also known as Edo-style sushi or Edomae-zushi.

Modern sushi was created by Hanaya Yohei (1799–1858) at the end of the Edo period. Previously, fresh-caught fish from Tokyo Bay was fermented in rice before consumption. In this era before refrigeration, Yohei prevented spoilage by slightly cooking or marinating the fish in soy sauce (shoyu) or vinegar (su).  He placed the fish on pads of vinegared (su) rice (shi), the style that became known as nigiri sushi.

 

This new sushi could be prepared very quickly, and eaten with one’s fingers. One of the first big consumer group was gamblers, who could roll the dice with one hand and eat with the other.

Those with more finesse used chopsticks (hashi).

 

Tidbit: The word nigiri derives from the Japanese verb “to grasp.” Unlike slicing sashimi or rolling a maki, the sushi chef has to grasp and squeeze the pad of rice before topping it with fish.

 

NIJIMASU
Rainbow trout. Regular trout is masu.

 

NORI
Dried sheets of purple laver seaweed used in the preparation of sushi rolls, known as norimake. The seaweed is the red algae genus Pyropia, including P. yezoensis and P. tenera.

The seaweed is washed and spread to dry, shredded and pressed into thins sheets (like the process for making paper), typically 8" x 8". The sheets are then toasted to enhance the flavor, texture and color of the seaweed. When toasted, the seaweed becomes black with green highlights.

 

 

NORI-TAMA
Nori-tama, sweetened omelet, is a slice of tamago sushi wrapped in a strip dried seaweed (nori). See tamago for how it is prepared. Each sushi bar makes its own tamago, and recipes can vary in small ways: amount of sweetness, doneness (the piece in the photo has darker marks in the yellow, indicating “well done”), and the degree of artistry in which the omelet is folded.

OCHA
Tea.
In Japan, this implicitly is green tea. There is no single green tea. As with black tea, there are different origins, and different ways treat the leaves to engender different flavor notes. Here’s more about green tea.

 

 

ODORI-EBI
“Dancing shrimp,” these are ama-ebi served and eaten alive. A Japanese custom, they are generally not served in U.S. establishments catering to Americans.

 

 

OHBA
Another word for the Japanese beefsteak plant, shiso.

OHITSU
Ohitsu is a special container to keep the sushi rice warm: a traditional round wood tub with a lid. The cooked rice is said to taste substantially better when placed in the ohitsu. Different regions use different styles originated by local craftsmen.

 

The style in the photo is from Sawara, a town in the Chiba Prefecture that prospered during the Edo Period (1603-1867) as a transport hub for rice shipments.

 

Today, some sushi bars and home cooks use electric rice warmers.

Halibut.

 

OMAKASE
Chef’s choice—pronounced o-MAH-kah-SAY. the chef prepares a selection based on the available fish of the day and his personal preferences. See photo at the top of the page. In addition to sushi, other courses—oshinko, tsukemono, a fruit dessert, etc.—are part of the meal. The western equivalent is the tasting dinner.

 

 

OKONOMI
The practice of ordering sushi a few pieces at a time. The opposite is moriawase (mo-di†-a-WAH-say) ordering a full  plate of sushi. Also see omakase, above.

†The flipped “r” is best pronounced like “d” for English speakers.

 

ONIGIRI
Rice balls or other shapes (squares, triangles) made with plain steamed rice and filled with various seasonings and stuffings: cooked fish and vegetables, nori, sesame seed and ume (plum paste). Some can be wrapped in nori or decorated with shredded nori, as in the photo of the ume rice ball, shown with two slices of pickled radish (takuwan).

 

In the early days of sushi, the fish was placed over balls of rice before the technique of flattened pads of rice (nigiri) was developed.

OSHIWAKU
A wooden box with a top used to make pressed sushi.
The rice is topped with any variety of fish, roe or vegetables, then pressed with the lid to adhere the ingredients. The pressed “cake” is then cut into squares or rectangles. See pressed sushi.

OSHINKO
Assorted pickled vegetables, which can be very salty. Another term for pickled vegetables is tsukemono. The latter are more accurately sliced and marinated, like a cucumber salad. Depending on the restaurant, the latter can refer to a salad of marinated cucumbers or bean sprouts. There are different types of tsukemono for sushi and cooked dishes. The oshinko typically served with sushi and sashimi include:

  • Benishoga, julienned strips of pickled ginger, colored red.
  • Gobo, pickled burdock root.
  • Kabu, pickled turnips
  • Kyurizuke, Japanese cucumber.
  • Nasuzuke, pickled eggplant.
  • Shibazuke, a mix of chopped, salted cucumbers and eggplant, brined with red shiso.
  • Takana, pickled mustard leaf.
  • Takuan, pickled daikon, colored bright yellow (photo at right).
  • Umeboskhi, pickled plum.
  • Yami-kurage, pickled stem lettuce.

 

Other vegetables are pickled as well, including Chinese/nappa cabbage and scallion bulbs. The pickled vegetable that everyone gets is gari, the pale pink pickled ginger served with sushi.

OSHI-ZUSHI
Osaka-style sushi, squares of pressed rice topped with vinegared or cooked fish. The sushi is prepared in a wooden box called an oshiwaku (the second photo at right), which can be square of rectangular in shape. It is then unmolded and cut into bite-size squares or rectangles.

 

There are different styles of pressed sushi, including:

  • Battera (topped with mackerel or gizzard shad and cut into squares or rectangles).
  • Bozushi (pressed into a long candy bar shape and cut into bite-size pieces).
  • Hazushi (layered with plant leaves), hakozushi (cut into squares or rectangles, Osaka style).
  • Masuzushi, traditionally made of vinegared trout on top of sushi rice

    In older times, the cut pieces were wrapped in bamboo leaves for travel. These days it is meal more often sold as ebiken, a type of boxed bento meal sold on trains and in train stations, to eat on the go.

  • Tazunazushi, with toppings placed on at a slant, resulting in “candy cane” stripes.

OTORO
This is the same as toro; the “o” is an honorific prefix used to give respect to an object or person. Of all fish, toro, the fattest and most prized portion of the tuna, deserves it. It is the from the lower belly of the tuna. As with beef, the marbling of fat makes the cut more tender. It is the priciest of sushi bar fish.

If otoro is the filet mignon of the tuna, then:

  • Chu-toro is the sirloin.
  • Akami is the chuck.
  • Kiriotoshi is the ends of the chuck, cut into chunks.

 

History: The high fat content means the fish spoiled quickly before the days of refrigeration. Everyone turned up their noses at the toro, and it was practically given away to impoverished laborers to eat.

PANKO
A crispy wheat breadcrumb used in Japanese cuisine. It is made in small flakes rather than ground into crumbs like traditional breadcrumbs, so it provides a crunchier coating.

Panko is used to provide crunch in some sushi rolls, either mixed in with chopped fish; sprinkled on other ingredients before they are rolled; or used on top as a garnish, as in the photo at right. More about panko.

 

 

PERILLA LEAF

PHILADELPHIA ROLL
A roll created in America, made of cream cheese (hence the “Philadelphia” brand reference) and either regular raw or smoked salmon.

 

PONZU
A sweet sauce made with Japanese citron.
