What Is Chestnut?
Chestnuts are edible nuts from trees in the genus Castanea, characterized by their spiny husks and smooth, brown shells. Unlike most nuts, chestnuts are relatively low in fat and high in carbohydrates, with a distinctly starchy texture when cooked.
"While often enjoyed roasted, chestnuts offer incredible depth when pureed into soups, incorporated into stuffings, or milled into flour for gluten-free baking."

To easily peel roasted chestnuts, score an 'X' on the flat side of each nut before roasting, then wrap them in a towel immediately after removing them from the oven; the steam will help loosen the skins.
