White coating on chocolate (chocolate bloom)
Occasionally, you may find a hazy, white coating on your chocolate. This is called chocolate bloom. Although it may affect the taste of chocolate, it is harmless and safe to eat.

How chocolate bloom occurs
Two things can cause chocolate bloom:
- If chocolate is exposed to high temperatures, the cocoa butter inside melts and separates from the rest of the ingredients. As a result, it settles on the surface in a hazy, white coating
- If there is an excess of moisture, it will cause the sugar in the chocolate to crystalize, which creates a white, speckled or spotted appearance on the surface of the chocolate
Although chocolate bloom may affect the taste of the chocolate, it does not pose a health risk. Chocolate that has bloom can still be eaten or used for baking.
How to avoid chocolate bloom
You can avoid chocolate bloom by storing your chocolate in a consistently cool and dry place.
