I need clarification please. I changed the designed of a birthday cake, instead of 2 tiers, it’s just one cake. I have to carry it to my job and store it in the refrigerator until the person collects it that day.
So, could the cake be stored in the refrigerator?
Yes, you can. I refrigerate all my fondant cakes until delivery. Just let them know to let it come to room temperature for optimal taste and texture. The fondant may show some condensation as it comes to room temp but it will dry and be perfectly fine. Don't touch it while it's wet as it may leave finger marks.
If you place it in a cardboard box wrapped in a layer of plastic wrap [and I would, especially since it will be in a communal refrigerator], they can leave it in the wrapped box till it comes to room temp. Any condensation will go to the box and the cake should be fine and dry when it's put on display.
