What must fondant icing be warmed to before being applied to a cake?

Fondant icing should be warmed to around 100°F before being applied to a cake. At this temperature, fondant becomes more pliable and easier to work with, allowing it to smoothly drape over the cake. When fondant is too cold, it can be stiff and difficult to manipulate, leading to cracking or uneven surfaces. Warming it to 100°F ensures the right consistency for easy handling and application, which is critical for achieving a polished and professional finish on the cake. Ensuring the fondant is at this temperature also helps it adhere better to the cake surface, creating a seamless look.
