The foundation to your awesome homemade sushi is the rice. If you don't create a sticky rice, rolling will be impossible. Take it from me... trying to roll sushi with rice that isn't sticky is wildly aggravating!
Thoroughly rinse the rice under running water. The water should run clear before you move on to the next step. If you don't remove the starch from the rice, it'll turn into a sloppy mess and will NOT become sticky enough to roll. RINSE IT!
Place the rinsed rice and water over high heat. Bring to a boil.
Once the water starts to boil, reduce heat to low and cook for 15 minutes
After the rice has finished cooking, remove from heat, leave covered and sit for 10 minutes
Combine rice vinegar, sugar and salt in a microwave safe bowl. Microwave for 30 seconds.
Once the rice has set for 10 minutes, mix with vinegar|sugar|salt
Place the rice into the refrigerator until cool. This will allow the rice to become nice and sticky. That will make the rolling process a lot easier!!
