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 the filling
Break the bread into a bowl and pour the boiling water over it.
Once softened, mash the bread into a pulp.
Add the sugar, butter, lemon juice, lemon zest, and beaten egg yolks to the pulp.
Bake and cool
Cover a pie plate with pastry, fill it with the mixture, and bake at 350°F (175°C) until set.
Let the pie cool.
Top with meringue
Make meringue by beating the egg whites with ice water and enough sugar to stiffen.
Spread the meringue over the cooled pie and return to the oven to brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks thicken the filling and egg whites whip into the meringue topping.
- Bread
- Softened and mashed, it gives the filling body and a soft, pulpy texture.
- Sugar
- Sweetens the filling and helps stiffen the meringue.
- Lemon
- Juice adds acidity and zest adds aroma to the filling.
- Butter
- Adds fat and richness to the filling.
The step that matters
Beating the meringue to stiffness. Egg whites need to be beaten with sugar until they form stiff, glossy peaks. Under-beaten whites weep or slump on the pie, while the sugar stabilises the foam so the topping holds its shape when browned.
Swap the lemon
How well each one fits the dish's main ingredients (bread, butter, sugar, egg):
- Vanillafits better
- Figfits better
- Datesfits about as well
- Lemonthe original
Fit is the average pairing score against bread, butter, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
