Hello I am wondering if fondant be refridgerated and also put in the freezer or will it ruin the pieces?? Thanks to all

It really depends. I live in a humid climate and when I take fondant out of the fridge there is condensation which, depending on what you use on e fondat, can be impacted. I still refrigerate all of my cakes. The condensation does dry. I would say you should test a small piece and see how it behaves for you. I use gumpaste mixed with fondant usually and it's been fine for me.
