Skin peaches by pouring boiling water over a few at a time and allowing to stand a few minutes. Then dip in cold water and skins will rub off. After peaches have been skinned, measure them and use one half of their weight in sugar. Have a large, clean, covered stone crock and put in a layer of peaches and a layer of sugar until all ingredients are used. Pour the brandy over the layers. Cover the crock with a heavy piece of white muslin before placing on the top of the crock. Set aside in a cool place and allow peaches to stand 2 to 3 months before using.
