A lot of people on the Internet say that you can just keep your cakes in a cool corner of your house; unfortunately this is sometimes not an option for those of us in Queensland, Australia. As a cake decorator in Brisbane, I provide the tips below to customers for storing their cakes between pickup and their event.
Fondant cakes stored in a humid and hot environment can end up looking like something out of a Salvador Dali painting, so proper storage is essential.
Applying a light dusting of cornflower can wick away moisture, but you should ensure you dust it off and shine the cake before serving. You cannot store a fondant cake in the fridge due to the moisture, but an air-conditioned room will be perfect. If you don’t have air-conditioning, a fan pointing directly at the cake in the coolest area of your house will suffice.
Cupcakes should be placed in an airtight container and kept at room temperature. Ensure that this is placed somewhere cool and dry. If the cupcakes are buttercream or ganache, these can be kept in the fridge, especially during summer, but you should ensure that you allow them to return to room temperature before serving for optimum flavour.
Buttercream & Ganache Cakes
Buttercream and ganache cakes should be iced as close to serving as possible. In hot environment these can be stored in the refrigerator but should be allowed to come to room temperature before serving. If storing for short period, you can keep it in an air-conditioned room.
Storing Sugar flowers
Moisture and heat are a sugar flower’s enemy. They will not harden and look very sad and tired if kept in a humid environment. Therefore when making or storing sugar flowers, you should make sure the room is dry and cool.
Try to place the flowers on the cake as late as possible to avoid humidity or heat. When storing the sugar flowers they should be placed inside an airtight container that contains rice, which will draw out moisture, helping to harden the flowers. When making larger flowers, place kitchen paper between the petals to help them stay open and to stop them sticking together.
If avoidable, don’t make or use fondant flowers when it is hot and wet. A Queensland summer storm is a fondant flower’s worst nightmare.
