Cooked chestnuts are best consumed on the same day, if you really can't eat them all, you can spread the chestnuts to save them, and do not put them in closed containers that are not ventilated, because cooked chestnuts generally contain water, and need to dissipate the heat, and if the heat dissipation is not good, it will naturally lead to deterioration of mold and rot.

Conditions can also be stored in the refrigerator, the next meal before heating, but this repeated heating will affect the taste.
