Stir in cranberries and lemon peel, return to a boil and then lower heat to simmer for an additional 10 minutes or until liquid barely covers raisins and cranberries. Remove from heat. Stir in chopped walnuts. Ladle into hot jars leaving 1/2" head space, wipe rims clean, seal and process in a water bath canner for 15 minutes. Makes 8 cups.
