OK... So I've been experimenting with different molds for Jems and using the Isomalt sticks. Today, I tried a CK jewel design breakup mold. It has a shiny finish and I thought it would make a shinier jewel. The problem was that it stuck in the mold. Only afterwords did I notice the instruction of "use oiled molds". My question is.... can I just spray on some veggie oil?? Or do I need to use something else?
