always choose the best-quality chocolate you afford. in general, European chocolate is less sweet and has a deeper, more refined flavor than American-made chocolate. Store chocolate in a cool, dry place away from light and odors. You can wrap it in aluminum foil as a further layer of protection. Never store it in your refrigerator or freezer. if chocolate turns whitish and cloudy , do not despair. Called "bloom," this discoloration occurs when chocolate has been stored in an environment that is humid or too warm, causing the cocoa butter to separate. The bloom will disappear when the chocolate is melted.
