Chocolate Fondue

12 ounces milk chocolate, semi-sweet chocolate or sweet cooking chocolate
1/4 cup half-and-half
1/2 cup sour cream
2 or 3 tablespoons orange-flavored liqueur, kirsch, brandy, white creme de menthe, 2 teaspoons dry instant coffee or 1/4 teaspoon ground cinnamon

Dipping items (strawberries, marshmallows, cookies, pound cake, etc...)

Heat chocolate and half-and-half in a heavy saucepan over low heat, stirring constantly, until chocolate is melted and mixture is smooth. Remove from heat; stir in liqueur or other flavoring. Pour into a fondue pot or chafing dish with water bath; keep warm over very low heat (NOTE: a crock pot set on low does a great job of keeping the fondue warm.) Stir in a small amount of cream if fondue becomes too thick while guests are dipping.
