What kinds of cake is Royal Icing most suitable for?

Royal icing is best suited for cakes that are smooth and flat. It's a firm, hard icing that's perfect for:

* Wedding cakes: Its smooth finish and ability to hold intricate designs make it ideal for wedding cakes.

* Anniversary cakes: Similar to wedding cakes, royal icing creates a polished and elegant look.

* Decorated cakes: Royal icing can be used to create detailed piping, lettering, and embellishments.

* Cookies: It's a popular choice for decorating cookies, as it hardens quickly and allows for intricate designs.

* Gingerbread houses: Royal icing is perfect for gluing together gingerbread pieces and decorating them.

Royal icing is not ideal for:

* Cakes with textured surfaces: It doesn't adhere well to textured surfaces, so it's not a good choice for cakes with fondant or buttercream frosting.

* Cakes that need to be transported: Royal icing can be fragile and can crack if the cake is bumped or dropped.

However, if you're determined to use royal icing on a cake with a textured surface, you can:

* Apply a thin layer of buttercream: This will provide a smooth surface for the royal icing to adhere to.

* Use a piping bag with a small tip: This will help to create a thin layer of icing that is less likely to crack.

Ultimately, the best way to determine whether royal icing is suitable for your cake is to consider the design and the desired finish.
