Are you a little hazy on what’s causing the buildup of a film on the surface of your chocolate moulds? You’re not alone. Learn what causes this common problem and get preventative tips on how to avoid it in this excerpt from RCI’s Mechanics of Chocolate Moulding course.
We all know the temperature of chocolate and, even, your workspace is important, but did you know the temperature of your moulds could also be affecting the quality of your chocolate?
Cold moulds can cause chocolate to stick to the surface of a mould because the chocolate has not had time to grow the proper crystals and shrink free of the surface. Moulds should be 75-80° F before coming into contact with chocolate. And, bonus, the solution to this problem is easy, because moulds within this temperature range will self clean. Repeated deposits will remove the buildup from the surface of the moulds.
Although cooking spray can work wonders for baking pans, never coat chocolate moulds with vegetable oil to prevent sticking. This may appear to help prevent buildup; but it will create early bloom on the surface of a moulded piece because of the incompatibility of the vegetable oil and the cocoa butter in chocolate. Compound coatings made with lauric fats, such as palm kernel oil, are even more susceptible to bloom than chocolate, if incompatible fats are mixed with them.
Now that you know your chocolate moulds like to be kept at a cozy 75-80° F, how do you check the temperature of a mould? An infrared thermometer "gun" will do the trick and can be found at any of your local home improvement stores. Click here to view best-selling infrared thermometers on Amazon. Prices range from $16 to $130.
