Royal icing is a fundamental component in cake decorating, serving both functional and aesthetic purposes. It acts as an adhesive, a decorative element, and a protective layer for cakes. Due to its versatility and the effort that goes into preparing it, understanding how to store royal icing and its shelf life is crucial for bakers and decorators. This article delves into the details of preserving royal icing, exploring its shelf life, storage methods, and the factors that affect its longevity.
Understanding Royal Icing
Before discussing the storage and shelf life of royal icing, it’s essential to understand what it is and how it’s made. Royal icing is a sweet white icing made from icing sugar and egg whites. It’s a popular choice for decorating cakes because it dries hard, making it ideal for intricate designs and as a base for other decorations like fondant. The basic ingredients of royal icing include powdered sugar, egg whites (or meringue powder as a substitute), and sometimes a small amount of water or lemon juice to achieve the desired consistency.
Preparing Royal Icing for Storage
To keep royal icing, it’s crucial to prepare it correctly for storage. This involves ensuring the icing is free of contaminants and is in a condition that minimizes the risk of it becoming too hard or developing an off taste. A common method is to wrap the icing tightly in plastic wrap or aluminum foil, making sure to press the wrap directly onto the surface of the icing to prevent air from reaching it.
