Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the filling as they set and add richness and color.
- Sugar
- Sweetens the filling and helps give it a smooth, set texture.
- Flour
- Thickens the filling so it holds its shape when cut.
- Vinegar
- Adds a sharp acidity that balances the sweetness of the filling.
The step that matters
Cooking the filling until it thickens. Egg yolks thicken as their proteins set with heat, but overheating can make them scramble and curdle. Stirring constantly over medium heat keeps the custard smooth and evenly thickened.
