Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemon
- Supplies juice and zest for tartness and bright aroma that balances the sweetness.
- Sugar
- Sweetens the filling and balances the acidity of the lemon.
- Egg yolks
- Thicken the filling and set it into a sliceable custard when heated.
- Butter
- Adds fat for richness and a smooth, tender texture.
The step that matters
Bake with an under crust until set. Egg proteins set as the filling heats, so the custard must be baked only until it firms. Overbaking tightens the proteins further, causing the filling to weep liquid or crack.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, egg, bread, butter):
- Vanillafits better
- Figfits better
- Datesfits about as well
- Lemonthe original
Fit is the average pairing score against sugar, egg, bread, butter. Candidates are from the same food group and used in at least 100 recipes.
