Why it works: Bread and butter 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
Cream the sugar and butter together.
Add the beaten yolks of the eggs and the fine bread crumbs.
Mix in the water, grated rind, and juice of the lemon.
Pour the mixture into a pie crust.
Top and bake
Beat the egg whites until stiff and spread over the top.
Bake until the top is slightly browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the filling and whites form a light, stiff topping that browns.
- Butter
- Adds richness and fat that softens the filling and gives a tender texture.
- Fine bread crumbs
- Absorb liquid and give the filling body so it sets rather than running thin.
- Lemon
- Provides the sharp acidity and aroma that define the pie's flavor.
- Sugar
- Sweetens the filling and helps balance the lemon's tartness.
The step that matters
Beat the egg whites until stiff. Egg whites must be beaten to firm peaks so they hold their shape and trap air. Under-beaten whites collapse and weep, while the sugar and heat set the topping.
Swap the lemon

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