Can I use Marshmallow fondant to make dried flower shapes for my wedding cake?
Yes, you can. The fondant will take a few days to dry hard, depending on how thick, maybe up to a week, but if they are just flowers with thin petals I’d guess less time – make a week ahead to be safe the first time. Store such that they can dry out but won’t get dusty, not in the refrigerator and not in an air tight container, lightly draped with plastic wrap or tin foil – once they are dried, store in an air tight container – if you want to be doubly safe get some silica beads and fill a new sock with them and tie it off, keep that sock in the air tight container to kill any moisture. You can buy silica at any craft store in the dried flowers section. I recently read that if you add gum traganth to the marshmallow fondant recipie to assist in the strength of the dried fondant (it’s an ingredient in gum paste, and can be purchased at Michael’s craft stores) – never tried it though. Gum paste (sugar paste) is easier and more versatile to mold, however – you might find some limitations
