Ingredients
6 cups confectioners' sugar
2 tablespoons Dutch-process cocoa powder
2 tablespoons light corn syrup
4 ounces unsweetened chocolate, finely chopped
Preparation
Whisk together sugar and cocoa in a medium saucepan. Whisk in 1/2 cup water and corn syrup; place over low heat and cook, stirring occasionally, until warm to the touch, about 4 minutes. Stir in chocolate until melted and smooth, about 1 minute more. Add additional warm water as needed to keep proper consistency, and rewarm as needed in a microwave or over a double boiler.
