How do you stop sweating fondant?

To stop fondant from sweating, ensure that it is stored in a cool, dry place away from humidity. If it has already started sweating, you can lightly dust it with cornstarch or powdered sugar to absorb moisture. Additionally, allow the fondant-covered cake to acclimate to room temperature in a controlled environment before serving. Avoid refrigerating the cake, as this can cause condensation when taken out.
