*If you don't have day-old rice, make 3 cups cooked rice from 1 cup dry. Rinse 1 cup of dry rice and combine with 2 cups water and a few shakes of salt in a small pot. Bring to a boil, stir once, cover, and simmer on low heat for 15 minutes. Turn off the heat and let stand for 5–10 minutes. Transfer to a sheet pan or pour into a large bowl and spread into an even layer (up the sides of the bowl if not using a sheet pan). Transfer to freezer for 15 minutes.
