Rice is the most fundamental component of sushi, and its preparation is easy if you pay close attention to the timing of each step. First, only Japanese style short grain rice should be used. When cooked, it is tender, moist and clingy, so it will hold its shape. In estimating quantities 1 cup of uncooked rice will yield about 3 cups cooked rice.
