Sushi, once considered an adventurous and somewhat intimidating dish, has now become a global staple. You can find it everywhere from high-end restaurants to your local grocery store. But beyond the basic recognition, many still wonder, “What exactly is sushi?”
At its heart, sushi is a celebration of specially prepared rice, often paired with seafood. While raw fish might be the first thing that comes to mind, it’s the meticulously crafted rice that truly defines sushi. In fact, the term “sushi” itself refers to the vinegared rice’s distinctive sour taste. Regardless of the toppings or fillings, rice is the non-negotiable ingredient in any sushi dish.
The art of sushi rice is so revered in Japan that aspiring sushi chefs dedicate years to mastering its preparation before they are even allowed to handle fish or other seafood. This dedication highlights the fundamental role rice plays in the world of sushi.
The Essential Sushi Rice
Sushi rice isn’t just any rice. It’s a medium-grain white rice, typically Japonica, and often the Koshihikari cultivar, meticulously seasoned with vinegar, salt, and sugar. This special preparation is what sets it apart and gives sushi its characteristic flavor.
Japonica rice is easily distinguishable from the long-grain indica rice more commonly consumed in Western countries. Its grains are shorter, rounder, and contain a higher proportion of amylopectin, a type of starch.
This higher starch content is key to sushi rice’s texture. As it cooks, Japonica rice becomes wonderfully sticky, making it ideal for shaping with chopsticks and holding together in various sushi forms. This stickiness is essential for both the eating experience and the artistic presentation of sushi.
Exploring the Diverse Types of Sushi
While all sushi shares the common thread of vinegared rice, the variations are vast and exciting. The two primary categories are nigiri and maki, each offering a unique way to enjoy this Japanese delicacy.
Nigiri: The Art of Hand-Pressed Sushi

Nigiri sushi, often simply called nigiri, is perhaps the most iconic form of sushi. It consists of an oblong mound of sushi rice topped with a slice of seafood, most commonly fish. While raw fish is typical, some nigiri features cooked seafood like eel or shrimp, or even fermented options.
The term “nigiri” in Japanese translates to “grip,” perfectly describing how this sushi is made. Nigiri-zushi literally means “hand-pressed sushi,” emphasizing the chef’s technique of hand-molding the rice and pressing the topping firmly on top. Sometimes, a touch of wasabi is added between the rice and the topping for an extra layer of flavor. The natural stickiness of the rice and the moisture from the topping help the ingredients adhere beautifully.
Popular nigiri toppings include classic raw fish like tuna, salmon, and yellowtail. For a richer experience, fatty tuna, sourced from the belly of bluefin tuna, is a highly sought-after choice. Nigiri is often garnished with delicate touches like minced scallions or ginger.
Interestingly, nigiri is traditionally meant to be eaten by hand, not with chopsticks, despite common practice. Soy sauce is an acceptable accompaniment, but etiquette dictates dipping the fish side into the soy sauce, avoiding soaking the rice and leaving loose grains in your sauce – a definite sushi faux pas.
Maki: The World of Sushi Rolls

Maki, in contrast to nigiri, is characterized by its rolled form. Rice and fillings are encased in a sheet of nori, a type of dried seaweed. Maki sushi offers a diverse range of styles.
Maki-zushi, the standard cylindrical sushi roll, is created by layering rice and fillings – which can range from raw fish and cooked shellfish to vegetables and even cream cheese – onto a sheet of nori. This sheet is then rolled tightly into a cylinder and sliced into bite-sized pieces.
Variations on maki include ura-maki, or “inside-out rolls.” In ura-maki, the rice is on the exterior, while the nori and fillings are nestled within. A popular example of ura-maki is the California roll. Like nigiri, maki is best enjoyed by hand, offering a casual and flavorful sushi experience.
Maki-zushi is further categorized by size into hoso-maki (thin rolls) and futo-maki (thick rolls), catering to different appetites and ingredient combinations.
Gunkan-maki, or “battleship rolls,” represent another maki variation. These are a hybrid between nigiri and maki. A hand-formed rice base is encircled by a strip of nori, creating a vessel to hold toppings that wouldn’t stay on a nigiri mound. These toppings are often softer or smaller, such as fish roe, finely chopped raw fish, or even creamy mixtures like sweet corn and mayonnaise.
Uni Sushi: An Acquired Taste of the Sea

Within the gunkan-maki category lies uni sushi, one of the more unique and often polarizing types of sushi. Uni is the Japanese name for sea urchin gonads, the edible sex organs of sea urchins. Uni has a distinctive tongue-like shape, a rich, sweet flavor, and a creamy, almost custard-like texture.
Harvesting uni is a labor-intensive process, making it a more expensive sushi option. However, for uni enthusiasts, the unique taste and texture are well worth the price. Freshness is paramount with uni; it should be firm and dry to the touch. Moist uni is a sign that it’s past its prime.
Temaki Sushi: The Fun of Hand Rolls

Finally, there’s temaki, or hand rolls. Unlike tightly rolled maki, temaki is made by loosely rolling nori into a cone shape, filling it with rice and other ingredients, much like a large, savory ice cream cone.

Sushi vs. Sashimi: Know the Difference
A common point of confusion is the difference between sushi and sashimi. Sashimi is not a type of sushi. The term sashimi, meaning “pierced meat” or “pierced body,” refers to thinly sliced raw fish or seafood served without rice. Sashimi is seasoned with soy sauce, wasabi, miso, or ginger, and is all about showcasing the pure flavor and quality of the fish itself.
In essence, sashimi is simply raw fish, often accompanied by seasonings and dipping sauces. Unlike sushi, which is hand-eaten, sashimi is traditionally eaten with chopsticks.

In conclusion, sushi is a multifaceted culinary art form that goes far beyond just raw fish. It is the harmonious combination of perfectly prepared vinegared rice and a variety of ingredients, from the familiar to the adventurous. Whether you prefer the simplicity of nigiri, the creativity of maki, or the unique experience of uni or temaki, the world of sushi offers something for every palate to explore and enjoy.
