Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Beaten into a foam, they trap air and give the filling a light, set structure.
- Sugar
- Adds sweetness and helps stabilize the beaten egg white foam.
- Grated chocolate
- Adds chocolate flavor and color to the filling.
The step that matters
Beat the egg whites until stiff. Stiff egg whites trap air that gives the filling its light, airy structure. Under-beaten whites stay runny and won't hold the mixture, while over-beaten whites turn dry and grainy.
