How to keep food in the dormitory without a refrigerator?
1, ventilation mode
Fill the washbasin with half a basin of tap water, then put the food into the bowl, cover it with gauze and put it into the basin. Finally, put the basin in a cool and ventilated place, so that the food will not go bad the next day, but the storage time is not long, usually about seven or eight hours.
2. Ginger method
You can buy some ginger and put it in the pot, so that even cooked rice can be eaten for more than one day. Because ginger is mild and spicy, it can be cooked with rice, so it is fragrant and not easy to go bad.
3. Fresh box method
Food can be sealed in a fresh-keeping box and then put in a cold water basin, so that food is not easy to go bad and can be stored for a longer time.
