Step By Step Instruction for Uni Sushi Roll

Preparing the Sushi Rice

Begin by washing the sushi rice until the water runs clear. This step is crucial to remove excess starch, which aids in achieving the perfect texture. Once clean, cook the rice according to your rice cooker’s instructions or on the stove, typically bringing it to a boil and then simmering until tender.

While the rice is still warm, gently fold in a mixture of rice vinegar, sugar, and salt to season. This combination provides the rice with the signature sushi flavor profile.

Shaping the Sushi Base

Lay out the nori sheet on a bamboo rolling mat with the shiny side down. Wet your hands to prevent sticking and spread a layer of sushi rice onto the nori, leaving a one-inch gap on all sides.

Adding the Fillings

On the rice, arrange your fillings starting with vegetables such as thin slices of cucumber or shredded spinach. It’s important to use a modest amount to avoid overfilling.

Next, delicately place the sea urchin roe, typically five pieces per urchin, evenly over the veggies. The roe should be fresh and handled with care.

Rolling the Sushi

Using the bamboo mat, roll the sushi into a tight cylinder, starting from the edge closest to you. Apply even pressure to ensure the roll is firm and holds its shape.

Slicing and Serving

With a sharp knife, slice the roll into bite-sized pieces. A dampened blade can make a cleaner cut through the sticky rice. Serve the uni sushi promptly with soy sauce, wasabi, and pickled ginger to complement the flavors.

Ingredient Substitute

When preparing an uni sushi roll, sourcing authentic ingredients ensures an optimal culinary experience. However, substitutes may be required when certain elements are not available. Here’s a guide to alternatives for different grades of uni and preparation styles like nama uni (fresh sea urchin), reito uni (frozen), yaki uni (grilled), and mushi uni (steamed).

Uni Grades

Original IngredientSubstitute OptionNotes
Grade A UniGrade B or C UniWhile Grade A has a firmer texture and brighter color, lower grades can be used. They typically have a softer texture and milder flavor.

Preparation Styles

How To Store Uni Sushi Roll

Proper storage is crucial for maintaining the freshness and quality of your uni sushi roll. Sea urchin, a delicate and perishable ingredient, is best enjoyed fresh, but if you must store it, follow these steps carefully.

Immediately After Preparation:

  • If not consuming the sushi rolls immediately, cover them with a damp paper towel to keep the rice from drying out.
  • Place the covered sushi in an airtight container to prevent any absorption of odors from your fridge.


  • Store the container of uni sushi in the coldest part of your refrigerator, which is typically at the back.
  • Make sure your fridge’s temperature is set below 4°C (39°F) to hinder bacterial growth.

Consumption Time Frame:

  • For optimal taste and texture, consume the stored uni sushi rolls within 24 hours.
  • As the uni sushi sits, there will be a gradual decline in quality. The sushi rice might lose its distinctive softness, and the sea urchin may not remain as creamy.

Caloric Consideration:

  • Be mindful that freshness affects not only taste but also the caloric content as the nutritional profile can change slightly over time.


  • Freezing is not recommended for uni sushi rolls, as it significantly compromises the quality of both the rice and the delicate sea urchin.

Remember, these steps are a guideline to help prolong your sushi’s life, albeit briefly. For the best experience, they suggest enjoying your uni sushi rolls freshly made.

When creating a uni sushi roll, various ingredients can be substituted to cater to different preferences or availability. For example, if uni (sea urchin roe) is difficult to obtain, consider using ikura (salmon roe) for a pop of briny flavor and a similar visual appeal.

In the context of uni pasta, a dish distinct yet related to uni sushi, substitutes could include a sauce enriched with sesame oil for a nutty undertone if uni butter is not at hand. The creamy texture of uni butter can be approximated by blending softened butter with roasted sesame oil and a pinch of salt.

Regarding the pasta itself, any long, thin noodle like spaghetti or linguine will serve as a solid foundation for the flavors of uni or its substitutes. It’s crucial to select pasta with a good surface texture to hold onto the sauce.

Here is a simple table outlining possible ingredient alternatives:

Original IngredientSubstitutePurpose in Dish
Uni (Sea Urchin Roe)Ikura (Salmon Roe)Briny flavor, unique texture
