Score, boil, and peel the chestnuts
20 minCut a crosswise slit in each chestnut shell; unscored chestnuts can burst while boiling. Boil in plenty of water for 20 minutes, until a fork pierces one easily. Remove the pot from the heat, but leave the chestnuts in the water. Take them out one or two at a time and remove both the outer shell and inner brown skin.
