What Does Otoro Mean?

Otoro is the fattiest part of the bluefin tuna, taken from the belly of the fish. The bluefin tuna is a massive fish, often reaching several hundred pounds in weight, and otoro is found in the lower portion of the tuna’s underbelly. It is the richest and most highly marbled cut, with a significant amount of intramuscular fat, giving it a melt-in-your-mouth texture that stands out from leaner parts of the tuna. In Japan, the bluefin tuna is broken into three main cuts:

• Akami: The lean, dark-red flesh found near the spine of the tuna.
• Chutoro: A more marbled, medium-fatty section from the back or belly.
• Otoro: The most marbled, rich, and expensive section from the belly.

Otoro’s deep flavor and creamy texture make it a delicacy, reserved for special occasions or high-end sushi bars.

What Does Nigiri Mean?

Nigiri (short for nigirizushi) refers to a style of sushi where a slice of raw fish is laid over a small mound of hand-pressed vinegared rice. The word nigiri itself means “to grasp” or “to squeeze,” which reflects the technique of forming the rice by hand. Unlike rolls (maki sushi), which are wrapped in seaweed, nigiri focuses on the balance between the fish and rice. Often, a bit of wasabi is tucked between the fish and rice, and the sushi may be gently brushed with soy sauce before being served.

In the case of otoro nigiri, the richness of the fatty otoro contrasts with the firmness and slight tartness of the vinegared rice, creating a harmonious balance in each bite.

History of Otoro Nigiri Sushi

Sushi has been evolving for centuries, but the style of nigirizushi as we know it today developed in Tokyo (then called Edo) during the early 19th century. During this period, fish was preserved with soy sauce, salt, or vinegar and combined with rice for quick consumption. Bluefin tuna wasn’t always the prized delicacy it is today. In fact, it was often considered a cheap fish for the masses or even used as cat food.

However, by the mid-20th century, sushi culture started to gain more prominence, and refrigeration methods allowed for better preservation of bluefin tuna, including its fatty belly cuts. Otoro, with its high-fat content, began to be recognized as a luxurious sushi option. Sushi chefs in Japan and around the world now regard otoro as a symbol of top-tier sushi, often offered at premium prices due to its scarcity and demand.

How to Make Otoro Nigiri Sushi

Creating otoro nigiri sushi is an art that requires skill and precision. The steps are simple, but each part must be executed perfectly for the best result:

1. Rice Preparation: Sushi rice is cooked and seasoned with rice vinegar, sugar, and salt. It’s then allowed to cool to room temperature.
2. Shaping the Rice: A small amount of sushi rice is formed into a tight oval mound by hand. It should be firm but soft enough to maintain its texture when eaten.
3. Slicing Otoro: The otoro must be cut into thin, delicate slices. The sharpness of the knife and the skill of the sushi chef play an important role in maintaining the integrity of the fatty tuna.
4. Assembling the Nigiri: A dab of wasabi is placed between the otoro and the rice, and the fish is laid gently over the top.
5. Final Touch: Some sushi chefs brush the fish with soy sauce or serve it with a small dip of soy sauce on the side.

The result is a piece of sushi that highlights the natural flavors of the otoro while maintaining the balance between fish, rice, and seasoning.
