Editor's Note: Dark, white or milk chocolate confectionery coating is found in the baking section of most grocery stores. It is sometime labeled "almond bark" or "candy coating" and is often sold in bulk packages (1 to 1-1/2 pounds). It is the product used for dipping chocolate. A substitute for 6 ounces chocolate coating would be 1 cup (6 ounces) semisweet, dark or white chocolate chips and 1 tablespoon shortening melted together. Truffles can be frozen for several months before dipping in chocolate. Thaw in the refrigerator before dipping.
