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 and enrich it, giving it a custard-like body and color.
- Sugar
- Sweetens the filling and helps balance the sharpness of the vinegar.
- Egg whites
- Whipped and spread on top, they form a light meringue that browns in the oven.
- Butter
- Adds fat for richness and a smoother, silkier texture in the filling.
- Vinegar
- Provides the acidity that gives this pie its tangy flavor.
The step that matters
Adding the boiling water gradually while stirring. Pouring hot liquid in too quickly can scramble the egg yolks. Adding it slowly while stirring tempers the yolks so the filling stays smooth and thickens evenly.

Fit is the average pairing score against sugar, egg, flour, butter, vinegar. Candidates are from the same food group and used in at least 100 recipes.
