For many, sushi was once an enigmatic dish, shrouded in mystery and perhaps a touch of apprehension. Today, sushi’s popularity has exploded, making it readily available even in your local supermarket. But with such widespread access, it’s natural to wonder: what is sushi exactly, and what are the different kinds?
Sushi is fundamentally a Japanese culinary art form centered around meticulously prepared rice, typically combined with seafood. While often associated with raw fish, sushi encompasses a broader spectrum, featuring both raw and cooked ingredients.
Contrary to popular belief, the essence of sushi isn’t solely about the fish – it’s actually the rice that holds the starring role. In fact, the very term “sushi” refers to the distinctive tangy flavor of the vinegared rice. Regardless of the diverse toppings or fillings, rice remains the indispensable component of any sushi creation.
Such is the significance of sushi rice that aspiring sushi chefs in Japan dedicate years to mastering its preparation before they even begin to handle fish or seafood. This rigorous training underscores the foundational importance of rice in the world of sushi.
The Crucial Role of Sushi Rice
Sushi rice isn’t just any rice; it’s a specially prepared medium-grain white rice seasoned with vinegar, salt, and sugar. The preferred variety is Japonica rice, particularly the Koshihikari cultivar, known for its ideal texture and flavor.
Japonica rice distinguishes itself from the long-grain indica rice more commonly consumed in Western countries with its rounder, medium-sized grains. The key difference lies in its starch content. Japonica rice boasts higher levels of amylopectin, a starch that imparts a delightful stickiness upon cooking. This stickiness is crucial for sushi, enabling it to be easily manipulated with chopsticks and expertly molded into various sushi shapes.
Exploring the Diverse Types of Sushi
While all sushi shares the common thread of vinegared rice, the world of sushi unfolds into captivating varieties, primarily categorized into nigiri and maki.
Nigiri: The Art of Hand-Pressed Sushi

Nigiri sushi is characterized by its elegant simplicity: an oblong mound of perfectly seasoned sushi rice crowned with a slice of topping, most often fish or seafood. While raw fish is prevalent, nigiri can also feature fermented or cooked toppings like eel or shrimp.
The term “nigiri” in Japanese translates to “grip,” perfectly describing the hand-pressed technique used to create this sushi. Nigiri-zushi literally means “hand-pressed sushi.” The sushi chef meticulously molds the rice by hand, then delicately presses the chosen topping onto the rice. A subtle touch of wasabi is sometimes added between the rice and topping, enhancing the flavor and acting as an adhesive. The natural stickiness of the rice and moisture from the topping ensure the topping adheres gracefully to the rice.
Popular nigiri toppings include classic raw fish like tuna, salmon, and yellowtail. For a richer experience, fatty tuna, sourced from the prized belly section of bluefin tuna, is a sought-after choice. Garnishes such as finely chopped scallions or ginger often complete the nigiri presentation.
Interestingly, despite the common use of chopsticks, nigiri sushi is traditionally intended to be eaten by hand. Soy sauce is a welcome accompaniment, but proper etiquette dictates dipping the fish side into the soy sauce, avoiding the rice. Leaving stray rice grains in the soy sauce is considered a cultural misstep.
Maki: The Delight of Sushi Rolls

Maki sushi, in contrast to nigiri, involves rolling rice and fillings within a sheet of nori, a type of dried seaweed. Maki presents itself in several captivating forms.
Maki-zushi typically takes a cylindrical shape, crafted by rolling nori around a layer of sushi rice and a medley of fillings. These fillings can range from raw fish and cooked shellfish to fresh vegetables and even creamy additions like cream cheese. Once rolled, the cylinder is precisely sliced into bite-sized rounds, perfect for sharing and enjoying.
A variation called ura-maki, or “inside-out roll,” features the rice on the exterior and the nori and fillings nestled within. Like nigiri, maki is best enjoyed using your fingers, allowing for a tactile and immersive eating experience.
Maki-zushi further branches into thin rolls, known as hoso-maki, and thicker, more substantial rolls, called futo-maki, catering to varying appetites and preferences.
Gunkan-maki, or “battleship rolls,” offer a unique maki variation. Resembling miniature battleships, they bridge the gap between nigiri and maki. A hand-molded rice base is encircled by a strip of nori, creating a vessel to hold toppings that might not adhere well to nigiri, such as delicate fish roe, finely minced raw fish, or even sweet corn kernels in a creamy mayonnaise dressing.
Uni Sushi: An Exquisite Delicacy

Within the gunkan-maki category lies uni sushi, a truly distinctive and often luxurious sushi experience. Uni is the Japanese name for the edible gonads, or sex organs, of sea urchins. Visually, uni resembles tongues, and it offers a unique flavor profile – sweet and subtly briny – with a slightly creamy, almost sticky texture.
The harvesting of uni is a labor-intensive process, contributing to its often higher price point. However, for uni aficionados, the unique taste and texture are well worth the indulgence. Freshness is paramount with uni; it should be firm and dry to the touch. Moistness is a telltale sign of diminished freshness.
Temaki Sushi: The Fun of Hand Rolls

Finally, there’s temaki sushi, or hand rolls, offering a more casual and interactive sushi style. Unlike maki, where nori is tightly rolled, temaki features nori loosely rolled into a cone shape, resembling a large ice cream cone, and filled with rice and ingredients. Temaki is perfect for home sushi making and parties, allowing for customization and a fun, hands-on experience.

Sushi vs. Sashimi: Clearing Up the Confusion
A frequent point of confusion revolves around the relationship between sushi and sashimi. It’s crucial to understand that sashimi is not a type of sushi. Sashimi, translating to “pierced meat” or “pierced body,” refers to thinly sliced raw fish or seafood, artfully seasoned with soy sauce, wasabi, miso, or ginger. The key distinction? Sashimi does not include rice. It’s purely about the pristine quality and flavor of the raw fish, enhanced by seasonings and dipping sauces. And unlike sushi, which is often enjoyed by hand, sashimi is traditionally eaten with chopsticks, emphasizing its refined and distinct nature.

It’s an intricate culinary tradition where vinegared rice takes center stage, complemented by a fascinating array of toppings and preparations. From the elegant nigiri to the playful temaki, the world of sushi offers a delightful journey of flavors and textures, waiting to be explored.
