Chocolate should be stored in a cool, dry place at a temperature of about 60F. If the chocolate becomes too warm, the cocoa butter rises to the surface and forms a dusty gray film known as "bloom." This "bloom" is not harmful and, once the chocolate is melted, it returns to its natural rich brown color. If you do store chocolate in the refrigerator or freezer, take in out and let it stand until it returns to room temperature before you use it in a recipe. Chocolate is very sensitive to sudden changes of temperature.
