Sushi rice, while not terribly exciting on its own, is the most important part of sushi. In Japan, recipes and techniques vary greatly and are often kept confidential. Start by buying good-quality short grain rice and make sure to rinse it well before you start cooking. After it’s cooked, it’s important that the vinegar mixture is ready and sprinkled evenly over the rice while barely being turned, so it’s well distributed to each grain of rice. If the end result is fluffy, shiny, and evenly flavored, then you’ve done it correctly.
