1. Microwave Thawing: Put the rice cake in the microwave oven, use the thawing function, adjust the time according to the size and hardness of the rice cake, and gradually thaw the rice cake to make it soft.
2. Steaming: put the rice cake in a steamer and cook it with medium fire. The steaming time depends on the size and hardness of the rice cake. You can check the hardness of the rice cake by inserting a toothpick.
3. Water bath heating: cut the rice cake into small pieces or pieces, put it in a heat-resistant container, add a proper amount of water, and heat it in hot water. The water temperature can be gradually raised, and don't overheat. Stir and turn the rice cake with a spoon until it is soft.
4. Stir-fried rice cake: cut the rice cake into small pieces or pieces, add appropriate amount of oil, stir-fry in a pot, add appropriate amount of water or broth, and heat and boil until the rice cake becomes soft.
It should be noted that in the above methods, microwave oven and water bath heating can solve the hardening problem of rice cakes quickly, while steaming and frying rice cakes take a longer time. In addition, attention should be paid to controlling the time and temperature during the heating process to avoid the rice cake from becoming too sticky due to excessive heating.
