What is a chocolate “bloom”?
There are 2 types of bloom – a sugar bloom and a fat bloom. A sugar bloom is usually caused by dampness and condensation – you’ll see grains of sugar on the surface of the chocolate. A fat bloom is usually caused by excessive heat or cold – you’ll see a whitish or gray film on the chocolate. Blooms are often mistaken for mold (which they are not) and are perfectly safe, although visually unappealing.
