Rice can be dry once it's refrigerated or frozen. Adding liquid will help to restream the rice and make it tender again. I usually add a few tablespoons of water, up to a quarter cup. Reheat in the microwave: Simply microwave the fried rice for about 2 minutes, loosely covered. Reheat on the stove-top: Add a little bit of oil to a skillet or wok. Add the rice and stir-fry until warm. Add a few tablespoons of liquid if the rice is dry and cover. Let the rice steam for a few minutes off the heat before serving.
