This sushi rice recipe is perfect for making homemade sushi rolls. Rinse 1 cup of sushi rice in cold water until the water runs clear. In a medium saucepan, combine the rice with 1 1/4 cups of water. Bring to a boil, then reduce the heat to low and cover the pot. Cook for 18-20 minutes, or until the liquid is absorbed and the rice is tender. In a small saucepan, combine 1/4 cup of rice vinegar, 1 tablespoon of sugar, and 1 teaspoon of salt. Heat over low heat until the sugar and salt dissolve. Stir the vinegar mixture into the cooked rice and let cool to room temperature before using for sushi rolls.
