Quality chocolate made with at least 32% cocoa butter.   To be properly labeled as “couverture”, it must contain 32-39% of cocoa butter, and the total of the percentage of the combined cocoa butter plus cocoa solids must be at least 54%.  Sugar makes up the balance, and up to 1% may be made up of vanilla, and sometimes soy lecithin.

Professional chocolatiers used couverture  for dipping, coating and molding.
