Ooops! You cooked the rice for a few minutes too long and now the burned rice is stuck to the bottom of the pot. The easier way to clean it is to pour a can of cola into the pot instead of the usual soak-scrub, soak and scrub again. Bring it into a boil, then remove from heat and let sit for 5 minutes. The cola’s phosphoric acid breaks down the burned-on food, so the residue slides right off.
