I made some gumpaste (egg, tylose, powdered sugar) to make some cake decorations. It says the gumpaste can be stored in the fridge up to 6 months. But how do I store the decorations Ive made until Im going to use them? I leave them out to dry after. But will they stay dry and all in room temperature for like a week?
Yep, they'll keep pretty much forever :)
room temp, in a box, not in refrigerator.
Yes, as crumbcake said, at room temp they'll be fine. It's just dried sugar, they will not go bad. Things that are very thin (like flowers) will be very delicate though. I have some toppers I did many many months ago under a cake dome and they look the same as the day I made them.
Just like everyone else said, it will last forever if you pack it carefully. Also make sure to store them air tight since sugar will attract moisture. I have saved a few decorations made years ago and they are stored in an air tight container in a closet. They look as good as the day they were made.
