How can I use a rice cooker to make perfect sushi rice?

To make perfect sushi rice in a rice cooker, rinse the rice well before cooking to remove excess starch. Use the correct ratio of water to rice, typically 1:1.1. Add rice and water to the cooker, then let it cook. Once done, let the rice sit for 10-15 minutes to steam. Finally, mix in seasoned rice vinegar and sugar while gently folding the rice to evenly distribute the flavors.
