Sea urchin, or uni, is one of the most luxurious and sought-after ingredients in sushi, known for its creamy, melt-in-your-mouth texture and sweet, oceanic flavor. Wrapping sea urchin in nori (seaweed) adds an earthy, briny flavor that complements uni’s delicate taste, creating a balanced and delightful sushi experience. This step-by-step guide will show you how to make restaurant-quality sea urchin sushi with nori at home, covering everything from selecting fresh uni to preparing sushi rice and mastering the nori wrapping technique.

Wrapping sea urchin in nori for sushi balances the rich creaminess of uni with a subtle briny flavor that enhances every bite. Unlike other sushi, uni sushi is traditionally wrapped in nori gunkan (or "battleship") style, allowing the delicate sea urchin to rest atop rice wrapped in a band of nori. This simple yet effective presentation holds the uni in place and allows its flavors to take center stage.
"Uni is one of the true delicacies of the ocean, with a flavor and texture that can only be enhanced by nori and perfectly seasoned rice," says Chef Masa Takayama, a renowned sushi chef known for his expertise in traditional Japanese cuisine.

The quality of ingredients plays a crucial role in making excellent sea urchin sushi. Here’s what you’ll need:
High-quality uni should be bright orange to golden yellow, with a creamy texture and a fresh, oceanic aroma. Avoid any uni with a dull color or strong odor, as this may indicate a loss of freshness.
Sushi rice provides a mild, slightly tangy base that complements the rich flavor of the uni. Choose short-grain Japanese rice for the best texture and stickiness.
For uni sushi, select high-quality nori sheets that are fresh, crisp, and slightly glossy. The right nori will add a hint of brininess without overpowering the uni.
Simple garnishes like shiso leaf, a small amount of wasabi, or a sprinkle of sesame seeds can enhance the sushi visually and add subtle flavors.

Follow these steps to create delicious sea urchin sushi with nori at home.
Prepare the Sushi Rice:
Rinse 1 cup of sushi rice under cold water until the water runs clear. Cook the rice and season it with rice vinegar, sugar, and salt. Allow the rice to cool to room temperature.
Shape the Sushi Rice:
Wet your hands to prevent sticking, and take a small amount of rice (about the size of a large marble). Gently form it into an oval shape, slightly flattening the top for a stable base. The rice should hold together but not be compressed too tightly.
Wrap the Nori Strip Around the Rice:
Wrap a strip of nori around the rice ball, leaving the top open. The nori should extend slightly above the rice to form a small “cup” to hold the uni. Press gently to secure the nori around the rice.
Place the Uni on Top:
Carefully place a piece of uni on top of the rice. Be gentle, as uni is delicate and can easily lose its shape. Position the uni to cover the top of the rice entirely.
Garnish and Serve:
If desired, add a tiny dab of wasabi on top of the uni or a sprinkle of sesame seeds for texture. Serve with a side of soy sauce or ponzu for dipping.

Making uni sushi requires a delicate touch and a few essential tips to bring out the best flavors. Here’s how to ensure your sushi is as delicious as it is visually appealing:
Uni is incredibly delicate. Use tweezers or a spoon to place the uni gently on the rice without breaking it. This helps maintain its shape and appearance.
Wet hands prevent the rice from sticking, allowing you to shape each sushi piece with ease. Use a small bowl of water nearby to keep your hands moist throughout the preparation.
The nori should be crisp and fresh, which adds a subtle crunch and briny flavor that complements the uni. Old or stale nori can be chewy and may detract from the texture of the sushi.
"Uni sushi is about balance—each element from the rice to the nori should complement the uni, not overpower it," advises Chef Nobu Matsuhisa, celebrated for his expertise in Japanese cuisine.

While uni is best enjoyed simply, a few subtle additions can enhance the experience. Here are some recommended accompaniments and garnishes for uni sushi:
A touch of wasabi adds mild heat that balances the creaminess of the uni. However, it should be used sparingly to avoid overpowering the delicate flavor.
