How To Make Sushi Rice

The Importance of Choosing the Right Rice: Japanese Varieties and Their Characteristics

Selecting the right rice is the first and most crucial step in preparing sushi at home. Using the wrong rice can completely ruin the experience, regardless of how well you follow the other steps.

Main Sushi Rice Varieties

Japonica Rice (Uruchimai)

This is the traditional and most recommended rice for sushi. It is characterized by its short grain and high starch content, which provides the ideal sticky texture needed to maintain the shape of sushi pieces.

Koshihikari Rice

A premium Japanese variety known for its soft and sticky texture, perfect for rolls and nigiri. Its short and round grain makes sushi preparation easier.

Calrose Rice

Developed in California, it's a popular Western alternative. It has a medium grain and mild flavor, being widely used in Japanese restaurants across the United States.

Essential Characteristics

The ideal sushi rice must have:

High starch content: To achieve the characteristic sticky texture.
Short to medium grain: Makes handling and compacting easier.
Absorption capacity: Must be able to absorb rice vinegar well without losing its shape.

Sushi rice is more than just an ingredient; it's the canvas upon which all the flavor and texture of sushi is built. Your choice will determine not only the final quality of the dish but also how easily you can work with it when forming the pieces.

The Perfect Water-to-Rice Ratio for Ideal Texture

The exact proportion of water to rice is crucial for achieving the perfect sushi texture. Each cooking method requires a specific amount of water to achieve the best results.

Proportions by Cooking Method

Traditional Pot:

One cup of rice needs 1.2 cups of water (240ml water per 200g rice).
Two cups of rice require 2.4 cups of water (480ml water per 400g rice).
Three cups of rice need 3.6 cups of water (720ml water per 600g rice).

Rice Cooker:

One cup of rice needs 1 cup of water (200ml water per 200g rice).
Two cups of rice require 2 cups of water (400ml water per 400g rice).
Three cups of rice need 3 cups of water (600ml water per 600g rice).

Pressure Cooker:

One cup of rice needs 0.8 cups of water (160ml water per 200g rice).
Two cups of rice require 1.6 cups of water (320ml water per 400g rice).
Three cups of rice need 2.4 cups of water (480ml water per 600g rice).

These proportions have been tested and perfected by sushi chefs over the years, ensuring that each grain of rice achieves the ideal sticky texture without becoming mushy.

The Detailed Rice Washing Process and Why It's Essential

Washing rice is a crucial step that cannot be skipped, as it removes excess starch and ensures the perfect texture for sushi rice.

Washing Process

First Wash: It must be quick and vigorous to remove surface impurities. It's important not to let the rice soak in this first water to prevent it from reabsorbing impurities.
Subsequent Washes: You should perform 6 to 9 washes, gently rubbing the rice with your palm to avoid breaking the grains. Each time, completely empty the water and refill the container.
Correct Technique: Use a non-metal colander and gently move the rice under running tap water. The process should continue until the water runs completely clear.

Why It's Essential

Starch Removal: Sushi rice has a high starch content that must be removed to achieve the correct texture. Inadequate washing will result in mushy and overly sticky rice.
Resting Time: After the final wash, it's essential to let the rice rest in the colander for 15 minutes. This step allows the grains to hydrate uniformly before cooking.

The difference between good and bad sushi begins with this washing process. Well-washed rice will be the perfect foundation for achieving sushi's characteristic texture: sticky but with defined grains.
