1, as the case may be. If it is raw chestnut, because it contains high moisture and sugar, it is not very resistant to low temperature below 0℃, so generally speaking, it is not recommended to store raw chestnut in the refrigerator, so as not to affect the taste and nutrition of chestnut. For cooked chestnuts, the starch contained in them will absorb water and gelatinize, so the water content of chestnuts will decrease. At this time, if they can't finish eating, they can be stored in the freezer of the refrigerator.

2. After freezing, the texture of chestnut is very hard. You can cook the frozen chestnut in hot water for a while. This can not only promote the thawing of chestnuts, but also make it easier to peel chestnuts after thermal expansion and cold contraction. After the cooked chestnuts are cooled, open a mouth on the chestnuts with a knife and remove the shells and skins of chestnuts by hand.
