Using Frozen Chestnuts
Once thawed, the chestnuts can be prepared and used in the same ways as chestnuts that have not been frozen. Chestnuts can be boiled, cooked in a microwave or roasted (grill, oven or open fire). According to Ask Nigel, frozen chestnuts can be added directly to stews from the freezer, if they have been boiled and shelled first.
Chestnuts can be eaten plain after roasting or can be used in any number of recipes. IGA recommends chestnuts with cream, coffee, vanilla, chocolate, nuts, pears, apples and dried fruit for a sweet-flavored match. For something more savory, pairing with meat such as veal, pork, lamb, game, and poultry are recommended.
Chestnuts are so versatile they can easily be used in tarts, stews, soups, meat dishes, vegetable dishes and desserts. They are potassium-rich and low in fat, making them a great nutritional choice.
