Which statement about bombes is incorrect?

The assertion that only a special bombe mixture can be used to fill a bombe is incorrect because bombes are quite versatile and can be filled with a variety of mixtures. A bombe typically consists of a molded dessert made with ice cream or mousse, which can incorporate numerous flavors and textures. The fillings can range from fruit purees to chocolate ganaches, allowing for creativity in construction. This flexibility in filling options is fundamental to the concept of a bombe, making it a unique and customizable dessert.

In contrast, the other statements are accurate. Bombes are indeed served frozen, which is essential to their structure and texture. They often exhibit a layered design, showcasing different flavors and colors, which is one of the distinguishing factors of this dessert. Finally, the ability to use a wide range of filling mixtures further highlights the versatility and creative potential of bombes, contrasting with the misconception that only a specific mixture can be used.
