What ingredient can you substitute for cornstarch when baking angel food cake?

You can't really substitute cornstarch for angel food cake. It's a key ingredient that provides the airy texture. Here's why:

* Structure: Cornstarch helps stabilize the egg whites, which is crucial for the cake's light and airy texture.

* Moisture Absorption: Cornstarch absorbs excess moisture, preventing the cake from becoming dense and gummy.

Instead of a substitute, you can try these alternatives:

* Use a different recipe: Many recipes exist for "angel food cake" without cornstarch. These typically rely on a slightly different technique, like using a bit more egg whites or adding a small amount of flour.

* Add a little flour: If you're desperate, you can add a tiny bit of all-purpose flour (1-2 tablespoons) to your recipe. This will make the cake slightly denser, but it might be your only option.

Remember: Using a substitute will likely change the texture and flavor of your cake. It's best to stick to a recipe specifically designed for a substitute or to find a different recipe altogether.
