I have a Gami Tempering machine I just recently purchased. It is wonderful, I might add. However, I have some vintage Christmas and Easter molds I have been playing with. Does anyone know the correct technique for using these old molds? I have tried filling the mold completely. I have tried pouring in chocolate and rotating around many times and pouring out excess. Each time, the chocolate figure comes out of the mold easily, but they all seem to crack. Sometimes in half, sometimes just a piece. Any suggestions?
