Does sushi rice increase in volume when cooked?

Yes, sushi rice does increase in volume when cooked.

Here's why:

* Starch Gelatinization: Rice grains contain starch granules. When cooked, these granules absorb water and swell, causing the rice to expand in volume. This is called gelatinization.

* Water Absorption: Sushi rice absorbs a significant amount of water during cooking, contributing to its increased volume.

The exact amount of volume increase will depend on:

* Type of rice: Different rice varieties have varying starch content and absorption capacity.

* Cooking method: The amount of water used and the cooking time will impact how much the rice expands.

* Ratio of rice to water: Using the right ratio is crucial for achieving the desired consistency.

Important Note: Sushi rice is traditionally cooked with a slightly higher ratio of water than other rice varieties to create a slightly sticky texture. This stickiness is essential for shaping sushi rolls.
