1. Wash the casserole with clean water when you buy it, and then put a pot of water to soak the casserole in the water for a day or two. ?
When cooking, first boil the water in the casserole, and then put the washed rice in the casserole. Stir the rice twice with a spatula or spoon before putting it into the pot to boil. Turn down the fire after the water boils, about 15-20.
After turning off the fire, wait for about five minutes, then take off the lid and let the rice stew in the pot for a while.
