4 cups sushi rice (Calrose/short grain)
Water, up to Mount Fuji (see below)
1 cup rice wine vinegar
1/4 cup mirin
1/2 cup sugar
*"MT FUJI" note: The Mt. Fuji method is a way to determine the correct amount of water for any quantity of rice. First wash the rice till the water runs clear to wash away all the starch. Then you put it in the pan, put your hand flat on top of the rice, and fill the pot with water until it reaches the first knuckle of your index finger (knuckle nearest your palm). It always works, no matter what the size of your hand.
