What causes bloom?
Fat bloom can be caused by several factors: * Temperature fluctuations can cause the fat to start to melt, the liquid fat moves easily to the surface. * Improper cooling can also cause bloom. As the coating solidifies slowly, portions of the fat stay in the liquid form longer and have the time to move to the surface. * Not properly melting the coating before you use it can contribute to fat bloom. * Sugar bloom is caused by moisture on the surface of the coating. Allowing the coating to get very cold as it sets and then putting it into a warm environment can cause condensation to form on the surface. * Improper storage can lead to both types of bloom. * To identify whether your product has fat bloom or sugar bloom you can warm the surface of the coating by gently rubbing your finger across it, or using a warm hair dryer. When the surface is heated, if the grayish appearance goes away, you have fat bloom. If the grayish appearance does not go away, it is sugar bloom.
