Using a small pairing knife, cut a cross or a line into the skin of each chestnut.
Once you have scored the outer shell, place the chestnuts in a bowl of hot water for 1 minute then drain and pat dry. This will help speed the cooking process and avoid burnt chestnuts.
Place the chestnuts in a single layer over a baking tray covered with aluminium foil, and gather up the edges to form a parcel slightly open on top. Bake them for 20 - 25 minutes, or until they tender.
You can also roast them in a traditional chestnut pan. Simply cook them over medium heat with a lid on, shaking the pan occasionally for about 30 minutes, or until they are tender.
Once they're ready, peel the skin off as soon as they cold enough to handle. Do it straight away as it's harder to peel them when they're cold.
How Long Do Roasted Chestnuts Last?You can enjoy chestnuts right away or store them in an airtight container in the coldest part of your refrigerator. They should last approximately 1-2 weeks.
