If rice is not sufficiently done, return cover and continue to cook a few minutes longer. To check amount of water left in pot, place spoon to the bottom of the pot and pull back the rice. To test for doneness, pinch a grain between your thumb and forefinger. If there is no hard core, the rice is done. Any form of white rice will keep indefinitely in a tightly sealed container on a pantry shelf.
Brown rice has a shorter shelf life because of the oil in the bran layer.
However, holding in a sealed container under refrigeration will greatly increase its shelf life. Storage of Cooked Rice Cooked rice will keep between 4 to 7 days under refrigeration when placed in a sealed container. Freezing Rice Make sure rice is well chilled before freezing, to avoid souring. Place in sealed containers. In a sauce pan mix two tablespoons of water for every cup of cooked rice.
