Well, that's pretty much it. i'm new to royal icing, and i was wondering about how long it took royal icing to dry. I'm using it to decorate sugar skulls (class project) and was wondering if it's something i can bring for my class to do (approx. 20 min for drying time) or if I should find something else to decorate with. Thanks!!!

Drying time will depend on the size of the pieces and the weather. If you're decorating with a small decorating tip (1-5) 20 minutes would probably be enough drying time. It will crust on the surface but will still be soft underneath. If it's rainy or humid with no air conditioning it may take a lot longer.

When I do production flowers (drop or roses) I plan on 12 hours for drying time. I do them at night, leave them on the table, and they are ready to put away by morning.
