I'm making a buttercream cake with Satin Ice accent decorations in a couple weeks. I just found out the cake will have to outside for over 4 hours! Does anyone know if the fondant will make it that long? I plan on using Indydebi's buttercream recipe so I know that will last! Just not sure about the fondant. I pray that it's not hot and humid that day!
I live in a very hot and humid place, and I use Satin Ice a lot. I "weather" proof it by adding a little extra powdered sugar (about 1/2 cup per pound of SI) and a little CMC (about 1/4 tsp. per pound). I haven't had any problems yet, but the outdoor cakes have always been in the shade. I don't think anything will withstand direct sunlight. HTH!
Fondarific is supposed to with stand up to 125 degrees. They do state that you need to keep it out of direct sunlight.
I assume it will be under a tent so that shouldn't be a problem. Thanks for your replies!!
