Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Lemon Pie
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Make the filling
In a bowl, combine the grated lemon rind, lemon juice, sugar, butter, water, egg, and bread crumbs, then mix until well combined.
Pour the mixture between two pie crusts.
Bake
Bake for 25 to 30 minutes until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Coagulates as it bakes, helping the filling set into a sliceable structure.
- Bread crumbs
- Absorb liquid and add body, thickening the filling.
- Sugar
- Adds sweetness and balances the sharpness of the lemon.
- Lemon juice
- Provides acidity and bright lemon flavor.
- Butter
- Adds fat for richness and a smoother mouthfeel.
- Lemon rind
- Contributes concentrated lemon aroma and oils to the filling.
The step that matters
Bake until set. The egg proteins coagulate as the filling heats, which firms it into a sliceable set. Underbaking leaves a runny center, while overbaking can make the egg curdle or weep and turn the texture grainy.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, butter, egg, bread):
- Vanillafits better

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