What is Foam Icing?

Published in Meringue Icing 2 mins read

Foam icing, often referred to as boiled icing, is a type of meringue primarily created by whisking eggs or egg whites with a hot, boiling syrup.

Understanding Foam Icing

At its core, foam icing is a specific kind of meringue. Unlike some other meringue types that might rely solely on sugar and egg whites, foam icings are distinctly made by incorporating a boiling syrup into the egg mixture. This method gives them their unique texture and stability, though they are also known by the simpler name of boiled icings.

Key Characteristics and Usage Tips

Understanding the attributes of foam icing is crucial for its proper preparation and application:

  • Meringue Base: It is fundamentally a meringue, specifically one made by combining a boiling syrup with an egg (or egg white) mixture.
  • Alternative Name: These icings are also widely known as "boiled icings," directly referencing the method of their creation.
  • Optional Stabilizers: To enhance their structure and slight longevity, some recipes for foam icings may include additional stabilizing ingredients, such as gelatin.
  • Application Method: For the best visual and textural results, foam-type icings should be applied thickly to cakes.
  • Decorative Finish: They are ideally suited for creating distinct peaks and swirls, adding an elegant and airy finish to baked goods.
  • Limited Stability: It is important to note that foam icings are not stable. This means they are highly perishable and should be used the same day they are prepared to ensure their quality and safety.

Due to their delicate nature and limited stability, plan to use foam icing immediately after preparation for the best results on your cakes.
