The difference between ice chestnuts and common chestnuts is the difference in nature and taste.

Properties: Frozen chestnuts are chestnuts after refrigeration or freezing, while ordinary chestnuts generally refer to chestnuts that have not been frozen;

Taste: Frozen chestnuts taste cold, even a little hard, while ordinary chestnuts taste soft, waxy and sweet, and have a sandy taste.

Frozen chestnuts may be easier to peel than ordinary chestnuts, and they can peel off complete nuts, so they are relatively simple to eat. Frozen chestnuts may taste like biting popsicles, but the frozen chestnuts are not as good as ordinary chestnuts and not so sweet.
