Frosting and Topping Food Facts
Frosting, also called icing, is a sweet, sugar-based mixture used to fill and coat cakes, pastries, cookies, etc. In addition to sugar, frosting can contain a combination of other ingredients including butter, milk, water, eggs and various flavorings.
Frosting can be cooked (as with boiled icing) or uncooked (as with buttercream), and can range from thick to thin.
Frosting must be thick enough to adhere to the item being coated, yet soft enough to spread easily.
Icing is defined as a sweet glaze made of sugar, butter, water, and egg whites or milk, often flavored and cooked and used to cover or decorate baked goods, such as cakes or cookies.
Topping is defined as a flavorful addition on top of a dish.
