Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into a foam that traps air, which gives the cake its light, airy structure.
- Sugar
- Sweetens the cake and helps stabilize the whipped egg white foam.
- Flour
- Sets during baking to form the cake's structure and hold its shape.
- Cream of tartar
- Acidifies the egg whites, stabilizing the foam so it holds more air.
The step that matters
Gently stir in the mixture until combined. The air trapped in the whipped egg white foam is what makes this cake rise. Stirring vigorously or over-mixing knocks out that air, leaving a dense, flat cake.
