I put all my cakes covered in fondant in the fridge, some sweating is totally normal, it’s cakes way to adjust to the room temperature… cake dries out with time, just don’t touch it when it has a lot of condensation, because you will leave permanent prints on it….
The other day I saw people posting this tip about a bottle of water, put it in the fridge until it gets totally cold, take it out and check how long time it will take for the bottle to dry (the condensation that builds up on the outside)… that way you will know how long time your cake will need to adjust to the room temperature.
Another trick is to put it in a cardboard box and seal with a plastic bag while it’s in the fridge, when you take it out, take off the bag but leave the cake in the box for a while until it adjusts…..
If you need a quick fix, you can try placing your cake in front of a fan but be careful not to blast it on and ruin your decorations.
Hope this helps, keep us posted :)
