Cake decorating can be challenging, especially when trying to achieve a picture-perfect finish. However, there is a game-changing tip that can make a difference. Working with a cold cake can help correct piping mistakes more easily. When a cake is chilled, the icing becomes firmer and less likely to stick, allowing for cleaner edges and more defined shapes. It's important to apply a crumb coat before chilling the cake and wrap it in plastic wrap to prevent unwanted flavors and odors. Chilling the cake for at least 30 minutes to an hour helps the icing set and firm up, resulting in a flawless masterpiece.
