Rinse the rice until the water is clear. (Normally takes 3 times)
Add oil, salt, vinegar in cold water. Normally the rice /water ratio is 1:1. It depends on the type of rice. White rice like sushi rice or jasmine rice are 1:1; brown rice, red rice or wild rice should be 1:2 (1 cup of rice with 2 cups of water)
Boil the rice by strong heat with cover on. Keep stirring every 2.3 mins to prevent rice from sticking in the bottom. You could see the water gradually drain out and some air holes being generated.(Normally after 7-8 mins)
Turn down the heat when you start seeing those air holes. Keep the cover on the whole time and watch the water boiling in the air holes. Turn the heat off when you stop seeing water coming out from the air holes.
Keep the cover on and let it sit for 20 mins. The steam will heat up the center of the rice hence its important to keep the cover on the whole time during the cooking process. Mix the rice evenly after 20 mins. Voil
