What is chocolate bloom?
Chocolate bloom is the tell-tale sign that chocolate has not been stored correctly. The most obvious type of bloom, fat bloom, looks like gray-white blotches and streaks on the chocolate and occurs when the chocolate is exposed to heat during storage. Sugar bloom, which leaves the chocolate feeling rough, occurs when the chocolate is stored in damp conditions. Melting and/or tempering bloomed chocolate eliminates the problem, although chocolate affected with sugar bloom should not be melted and used for fine candy making.
