Ingredients

　　Place finely chopped (white or dark) chocolate (or use whole chocolate chips if called for in a recipe) in a heatproof bowl set over (not in) a pan of simmering water (do not let any water come into contact with the chocolate, or it may seize, or harden). Heat until chocolate is almost melted, then stir with a flexible spatula until completely melted. Remove bowl from pan, and let chocolate cool, stirring occasionally, about 30 minutes before using.
