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 and bake the filling
In a bowl, mix sugar, butter, egg yolks, lemon juice, lemon rind, hot water, and grated bread until well combined.
Pour the mixture into a pie crust and bake until set.
Top and brown
Whip the egg whites until stiff peaks form, then sweeten to taste.
Spread the meringue over the baked 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
- Yolks thicken the filling and whites whip into a stable meringue topping.
- Sugar
- Sweetens the filling and helps stabilize the whipped egg whites.
- Lemon
- Juice and rind provide the acidity and bright citrus aroma.
- Bread
- Grated bread soaks up liquid and gives the filling body and structure.
- Butter
- Adds fat for a richer, smoother texture in the filling.
The step that matters
Whip the egg whites to stiff peaks. Egg whites must be free of yolk and fat to whip fully. Under-whipped or greasy whites will weep or collapse, leaving a loose meringue that does not brown cleanly.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, butter, egg, bread):

- Figfits better
- Datesfits about as well
- 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.
