I have a sushi rice bag from Sun Rice. They write on it that we should only wash it for 5 minutes then boil it. But I know that sushi rice should be washed for more than that and soaked in water for at least 2 hours. I did it and left it for 2 hours. Then I boil it (1 cup of rice to 1 and 1/4 cup of water). But when I started making the sushi, the rice started to expand and not sticking to each other.
The problem is because of the 2 hours or I didn't left the rice cook until all the moisture gone ?
