What Is Sushi Making?

Sushi making is the culinary art of preparing sushi — the Japanese dish built around vinegared rice combined with raw or cooked seafood, vegetables, and other ingredients. The word “sushi” actually refers to the seasoned rice, not the fish. That distinction matters: sushi without fish is still sushi. Fish without rice is sashimi.

What looks simple on the plate — a few pieces of fish on small mounds of rice — actually represents one of the most technically demanding cuisines in the world. Every element, from the rice temperature to the knife angle to the wasabi placement, follows precise traditions refined over centuries.

The Rice Is Everything

Ask any sushi chef what the most important element is, and they’ll say the rice — shari or sumeshi. Getting it right is an obsession.

Sushi rice is short-grain Japanese rice (varieties like Koshihikari or Calrose) cooked to a specific texture, then seasoned with a mixture of rice vinegar, sugar, and salt while it’s still warm. The seasoning must be folded in gently with a cutting motion — stirring destroys the grain structure.

The finished rice should be sticky enough to hold its shape, loose enough to separate in your mouth, and served at body temperature. Too cold and it’s dense. Too warm and the fish on top deteriorates faster. In traditional sushi restaurants, the rice is made fresh throughout the day.

Japanese sushi apprentices historically spend the first several years of their training solely on rice preparation before touching any fish.

Types of Sushi

Nigiri

The iconic form: an oblong mound of rice topped with a slice of fish or seafood, sometimes with a thin smear of wasabi between them. The chef shapes each piece by hand in seconds — pressing firmly enough to hold together but gently enough that the rice stays airy.

Maki (Rolls)

Rice and fillings wrapped in nori (dried seaweed) and sliced into rounds. The Western obsession with elaborate rolls (dragon rolls, rainbow rolls, deep-fried everything rolls) is almost entirely an American invention. Traditional Japanese maki are simple: a single ingredient wrapped in rice and nori.

Temaki (Hand Rolls)

Nori shaped into a cone and filled with rice, fish, and vegetables. Eaten immediately — they lose their crunch within minutes as the nori absorbs moisture.

Chirashi

Assorted sashimi scattered over a bowl of sushi rice. Popular as a lunch dish in Japan — faster to prepare than nigiri and just as delicious.

Oshi-zushi

Pressed sushi — rice and toppings compressed in a wooden mold, then sliced into rectangles. This is actually closer to sushi’s historical origins than nigiri is.

The Fish

Quality fish is essential, but “sushi-grade” isn’t a regulated term in the U.S. What it generally means is that the fish has been frozen to FDA-recommended temperatures (-35°C for 15 hours, or -20°C for 7 days) to kill parasites.

Common sushi fish include tuna (maguro), salmon (sake), yellowtail (hamachi), shrimp (ebi), eel (unagi), and squid (ika). A skilled chef selects fish by examining color, texture, smell, and fat content. Otoro — the fatty belly of bluefin tuna — is considered the finest cut and can sell for hundreds of dollars per pound.

Knife Skills

The sushi knife (yanagiba) is a single-beveled blade — sharpened on only one side — designed for making clean, precise cuts through fish. A dull knife crushes the fish cells, releasing moisture and ruining texture. A sharp yanagiba makes a cut so clean the surface actually glistens.

Professional sushi chefs sharpen their knives daily on whetstones, a meditative routine that’s part of the craft. A good yanagiba costs $200-$2,000+ and is treated with serious care.

A Brief History

Sushi’s origins are in fermentation, not fresh fish. The earliest form, narezushi, dates to Southeast Asia around the 2nd century — fish packed in salted rice and left to ferment for months. The rice was discarded and only the fish was eaten.

Over centuries in Japan, the fermentation time shortened. By the Edo period (1603-1868), a faster version using vinegared rice became popular. In the 1820s, a chef named Hanaya Yohei in Tokyo began making nigiri-zushi — fresh fish pressed onto seasoned rice — sold as fast food from street stalls. This is essentially the sushi we know today.

Sushi Making at Home

You don’t need a decade of training to make decent sushi at home. A rice cooker, quality short-grain rice, rice vinegar, nori sheets, and fresh fish from a trusted fishmonger will get you started. Maki rolls are the most beginner-friendly — a bamboo rolling mat (makisu) costs a couple of dollars and makes the technique much easier.

The gap between homemade and professional sushi is real, though. It’s the difference between playing guitar in your bedroom and performing at Carnegie Hall. Both are enjoyable. One takes considerably more practice.

Frequently Asked Questions

Is it safe to eat raw fish in sushi?

Yes, when handled properly. Sushi-grade fish is typically flash-frozen at extremely low temperatures (-35°C for 15+ hours) to kill parasites, per FDA guidelines. Professional sushi chefs are trained in safe handling, storage, and inspection. The risk of foodborne illness from properly prepared sushi is very low — comparable to or lower than many cooked foods.

How long does it take to become a sushi chef?

In traditional Japanese training, becoming an itamae (sushi master) takes 10+ years. Apprentices spend years just learning to prepare rice before they're allowed to touch fish. Modern training programs can teach the technical basics in months, but the depth of knowledge, knife skills, and palate development that distinguish a true master takes many years.

What is the difference between sushi and sashimi?

Sushi always includes vinegared rice — the word 'sushi' actually refers to the rice, not the fish. Sashimi is sliced raw fish or seafood served without rice. A piece of salmon on rice is sushi (nigiri). A slice of salmon on its own is sashimi. Sushi can also be vegetarian — the rice is the defining ingredient.
