Food wrapped in tin foil can be heated in the oven. Put the food wrapped in tin box into the oven and heat it up and down for about 10 minute. You can put the tin box into the steamer, calculate the time after the water is boiled, and steam for about 10 minute to complete the heating; You can also fry the tin box in a frying pan until it is heated.

You can also heat it with hot water, add appropriate water to the pot, and after the water boils, put the iron box with rice into the boiling water. Remember to cover it. Boiling water and steam can heat food quickly.

Tin foil can't be heated in the microwave oven.

Tin paper is a kind of metal paper similar to film, and its composition is actually aluminum, not tin. The resistance of tin foil is low, and the microwave oven can reflect metal, so it cannot be easily heated in the microwave oven unless the barbecue function of the microwave oven is used. At present, ordinary microwave ovens have no barbecue function, and only intelligent micro-steaming-roasting integrated microwave ovens have barbecue function.

If the tin foil is forcibly put into the microwave oven for heating, it will lead to uneven heating in the microwave oven and uncooked food; In severe cases, the microwave oven will catch fire, damage the magnetron of the microwave oven and cause serious safety accidents.
