Chestnuts fried with sugar can be kept in the refrigerator for a long time, and can be taken out and put in the microwave when eating. It is recommended to eat sugar-fried chestnuts within a week, otherwise it will affect the taste.

If the indoor temperature is suitable, the chestnuts can be spread out and stored, and it is not advisable to pack them in closed and unventilated bags or other containers, because the cooked chestnuts generally contain moisture and need heat dissipation. Poor heat dissipation will naturally lead to deterioration and mildew.
