Whole raw Turkish chestnuts (kestane) in the shell, ready for roasting at home. Turkey is one of the world's largest chestnut producers — FAO data ranks it fourth globally, with roughly 71,000 tonnes harvested in 2023 — and the chestnut is woven deep into Turkish winter life. From late autumn, street carts across Istanbul roast scored chestnuts over coals and hand them out in paper cones: kestane kebabı, one of the country's oldest street foods. In Bursa, the same nut becomes kestane şekeri, the famous candied chestnut simmered in sugar syrup. These are the same whole, unprocessed chestnuts — glossy mahogany shells, dense ivory flesh — for you to roast, boil, or candy yourself. How to roast them: cut an X through the shell on the rounded side of each chestnut (this stops them bursting and makes peeling easy), then roast at 200°C / 400°F for about 20–25 minutes until the shells curl open at the cut. Peel while still warm — the inner skin releases far more easily than when cold. A handful of hot chestnuts on a winter evening needs nothing else, though they also work boiled into soups, folded into pilaf or stuffing, or pureed for desserts. What chestnuts are: unlike almonds, walnuts, and other tree nuts, chestnuts are mostly starch and water, with far less fat — closer to a grain than a typical nut. They are naturally gluten-free. Storage: fresh chestnuts are perishable. Keep them refrigerated in a perforated or breathable bag and use within two to three weeks, or freeze for up to six months. Available in 250 g, 500 g, and 1 kg packs. Note: fresh chestnuts are a seasonal harvest product — availability follows the autumn–winter chestnut season.
