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

Directions
Prepare the filling
In a bowl, mix the egg, sugar, water, bread crumbs, lemon juice, and grated rind.
Pour the mixture into a pie crust to make three pies.
Make the lemon jelly
In a saucepan, combine the grated lemon, sugar, cornstarch, butter, and cold water.
Cook over medium heat until the mixture thickens into a clear jelly.
Top and finish
Beat the egg whites until stiff, then gradually add the sugar.
Spread the meringue over the pie filling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into a stiff foam that forms the light, airy meringue topping.
- Cornstarch
- Thickens the cooked lemon mixture into a clear, sliceable jelly.
- Sugar
- Sweetens the filling and helps stabilize the whipped egg whites.
- Lemon juice
- Adds acidity and sharp lemon tartness to balance the sweetness.
- Bread crumbs
- Absorb liquid and give the filling body.
The step that matters
Cooking the lemon jelly until clear and thick. Cornstarch only thickens fully once the mixture reaches a simmer and is held there briefly. Undercooked starch stays runny and can make the filling weep or slump when cut.
Swap the lemon
How well each one fits the dish's main ingredients (egg, sugar, bread, butter):
- Vanillafits better
- Figfits better
- Datesfits about as well
- Lemonthe original
Fit is the average pairing score against egg, sugar, bread, butter. Candidates are from the same food group and used in at least 100 recipes.
