Cranberry Shiver

Preparation : In a saucepan, bring cranberries and 2 cups of water to a boil. Reduce heat; simmer for 5 minutes. Press though a strainer to remove skins; discard skins. To the juice, add sugar, lemon juice, orange peel and remaining water; mix well. Pour into an 8 inch pan. Cover and freeze until ice begins to form around the edges of the pan, about 1 1/2 hours, stir. Freeze until mushy, about 30 minutes. Spoon into freezer container; cover and freeze. Remove from the freezer 20 minutes before serving. Scoop into small dishes; garnish with mint if desired.
