Edible glue is great when affixing lighter or smaller elements together, especially when they don’t have gravity to compete with. For larger and heavier objects like attaching sugar roses to the sides of cakes etc candy melts are a cake decorator’s best tool! It’s strong, dried quickly and can be re-tempered when needed again.
“Use candy melts to attach heavier and larger edible decorations that need to defy gravity. Candy melts are strong, dry quickly and can be re-melted when needed!”
