Royal Icing
Description
Royal icing is a pure white and fluid paste that hardens into a smooth, hard, matte finish when dried. It is made from powdered sugar (icing sugar), egg whites or meringue powder, and water. Sometimes, lemon juice or other flavorings are added for taste. Royal icing can be adjusted to various consistencies; thinner for flooding the surfaces of cookies, or thicker for detailed piping work. It is widely used for decorating cakes, cookies, and gingerbread houses, offering a palette for intricate designs and decorations.
In terms of measurements, royal icing recipes often require precision. For instance, one might need 4 cups (approx. 480 grams) of powdered sugar, 3 tablespoons (approx. 30 grams) of meringue powder, and 5-6 tablespoons (approx. 75-90 milliliters) of water. It's essential to use the correct units for consistency, whether following a recipe in metric (grams, milliliters) or imperial/American (cups, tablespoons) measurements.
Common uses
Royal icing is commonly used in cake decorating, for creating flowers, piping borders, and writing. It's also the glue that holds gingerbread houses together and is used to flood cookies with a smooth, hard surface that can be further embellished with more detailed piped designs.
