What are Chestnuts?

Chestnuts are not your typical tropical nut. They are a cool-season edible nut found in the Northern Hemisphere, in the hilly forests of North America, Europe, China and Japan. Frosts and snowfalls are beneficial to the chestnut tree and enable them to produce better crops. Chestnuts are encased in a prickly outer casing, called a burr, that falls to the ground and opens up once they ripen in the autumn. Inside the burr, the chestnut is shiny with a brown peel and the inside is creamy white and starchy tasting.

There are 4 different varieties of chestnut growing all over the world, the more common one being sweet chestnut. Do not confuse edible chestnuts with horse chestnuts because they are completely different plants and horse chestnuts are toxic.

Chestnuts have a long history in Europe and were even mentioned by Galen, a prominent Greek physician during the Roman Empire. Historically, chestnuts were an important carbohydrate-rich food for forest dwellers in Europe, who did not have access to starchy foods like wheat or potato. Chestnut bread was a common food in Europe and in some areas, sweet chestnut trees were called “The bread tree”. In both France and Japan, chestnuts are served as a delicacy at New Year's celebrations because the peak season of availability is in December.
