Heat chocolate and half-and-half in 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 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.
Variation: Chocolate-Sour Cream Fondue. Substitute 1/2 cup dairy sour cream for 1/4 cup of the half-and-half.
Dippers: strawberries, banana slices*, pineapple chunks, mandarin orange segments, fresh orange slices, apple wedges*, grapes, melon balls, papaya wedges*, maraschino cherries (I also love fresh pitted Bing cherries!), kiwifruit slices, fresh coconut chunks, pound cake cubes, ladyfingers, miniature cream puffs, miniature doughnuts, marshmallows, pretzels, angel food cake cubes and vanilla wafers. All the fruits followed by a * should be dipped in lemon juice after cutting to prevent oxidation.
