Eight ounces of fresh chestnuts yields about 1 cup peeled and cooked. With a small knife, score a cross on the flat side of each chestnut. Using a slotted spoon, dip chestnuts, 4 or 5 at a time, into a saucepan of boiling water. Peel away shells and inner brown skins. If chestnuts are difficult to peel, return them to boiling water for a few seconds. Place peeled chestnuts in a large saucepan and add enough water to cover. Simmer, covered, until tender, 30 to 45 minutes. Drain and refresh with cold water.
