Having very allergic dd. I am very tempted on trying to melt choc and buy some molds this coming easter. Anyone have any sugestions/advice. Have I anything to worry about buying silicone molds? Dd is allergic to lots of things and has a risk of latex allergy due to kiwi and bannana allergies. Is silicone ok or would you stick to the metal looking molds. Anyone have any tips,advice or good websites?
