You can add icing sugar to a cake in several ways, depending on the desired effect. It's primarily used for sweetening and decorating.
Here's a breakdown of the common methods:
-
Dusting for Sweetening and a Simple Finish:
- This is the simplest method.
- Sifting is crucial: Use a fine-mesh sieve or a specialized icing sugar duster. This prevents lumps and ensures an even, light coating.
- Application: Gently tap the sieve or duster over the cake to distribute the icing sugar.
- Timing: Apply just before serving, as the sugar can dissolve if applied too far in advance, especially on moist cakes.
-
Making Royal Icing for Decoration:
- Icing sugar (also known as powdered sugar or confectioners' sugar) is the primary ingredient in royal icing.
- Recipe: Royal icing typically consists of icing sugar, egg whites (or meringue powder), and a touch of lemon juice or water.
- Mixing: Combine the ingredients and mix until you achieve a smooth, pipeable consistency. The exact consistency will depend on the specific decorating task.
- Application: Use piping bags and tips to create intricate designs on cakes and cookies. Royal icing hardens as it dries, creating a firm and decorative finish.
-
Making Simple Glazes:
- Icing sugar can be mixed with a liquid (such as water, milk, lemon juice, or coffee) to create a simple glaze.
- Consistency: Adjust the ratio of icing sugar to liquid to achieve the desired thickness. A thinner glaze will be more translucent, while a thicker glaze will be more opaque.
- Application: Drizzle the glaze over the cake using a spoon or fork.
Important Considerations:
- Lumps: Always sift icing sugar to remove lumps before using it in any recipe or application.
- Moisture: Be mindful of moisture. Icing sugar absorbs moisture, so store it in an airtight container. Also, applying it to very moist cakes well in advance can lead to a soggy or dissolved appearance.
- Variations: Some recipes might require specific types of icing sugar, such as one with added cornstarch. Check your recipe carefully.
