You followed the recipe perfectly, tempered your chocolate carefully, and set your bonbons to cool. But when you pull them out, they are covered in a dusty white film. What happened?
Chocolate bloom is one of the most common frustrations for home chocolatiers. There are two distinct types: fat bloom (whitish, greasy coating from cocoa butter separation) and sugar bloom (granular, rough texture from moisture condensation).
Prevention Strategies
- Perfect your temper: Use a reliable thermometer and hit target temperatures precisely. Dark chocolate should be worked at 31-32 degrees C.
- Cool slowly: Let finished chocolates set at room temperature (18-20 degrees C) rather than rushing them into the fridge.
- Control humidity: Store chocolate in a cool, dry place. Never store unwrapped chocolate in the fridge alongside other foods.
- Avoid temperature swings: If you must refrigerate, wrap tightly in plastic wrap first, and let it return to room temperature before unwrapping.
