Chestnuts are produced by seven tree species within the genus Castanea. They have a creamy white flesh that appears in several cuisines, the most popular being roasted as a holiday food. Chestnut trees also provide valuable timber. Chestnuts can be found for sale in different forms, depending on the region of the world where the consumer is located. During the winter, many Northern Hemisphere countries have fresh whole chestnuts for sale, but you can also find chestnuts preserved in water or syrup or ground into flour.
The Northern Hemisphere is home to a number of distinct chestnut species, which have intermingled due to human introduction of favored trees to different regions. All trees in the genus are deciduous, which means they shed their leaves every winter. The chestnut leaves are simple and broad, with slightly serrated edges. A related species, the chinkapin, native to the American Northwest, looks very similar. The trees produce catkins, which ripen into chestnuts in the fall. Each individual chestnut is encased in a prickly husk, which opens to reveal the brown-hulled nut inside.
When sorting whole chestnuts, consumers should look for smooth, shiny specimens that don’t crackle inside the hull. Depending on the region, whole fresh chestnuts can be found roughly between September and February. Before being hulled, the nuts can be stored in a cool, dry place and after the hulls have been removed, they should be refrigerated. The chestnut flour must be kept in the refrigerator until it is used. It can be used in ethnic recipes or much like conventional flour.
One of the most classic preparations for chestnuts is roasting. To roast chestnuts, the hulls are cut so that they do not explode during roasting, either in the oven or in the fire. They are placed in a skillet and roasted for about 25 minutes, until the hulls are darker and more brittle. Consumers should be advised that chestnuts are extremely hot and should not be peeled immediately, despite the intoxicating aroma.
In some ethnic cuisines, a ground chestnut-based flour is used. Chestnuts are also used in Italian ice cream and can be ground into pastes, used in desserts, added to fillings, and in many other dishes. Savory chestnut dishes like ravioli are popular in Italy, especially with delicate creamy sauces that bring out the natural flavor of the sweet nuts.
