Why it works: Butter and lemon are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 41,227 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Lemon Pie with Two Crusts
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 butter and sugar together in a bowl.
Add the lemon juice and rind, then mix in the egg yolks.
Fold in the beaten egg whites gently.
Assemble and bake
Pour the mixture into one of the pie crusts and cover with the second crust.
Bake until the crust is golden and the filling is set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg proteins set during baking to firm the filling, and the whites add lightness.
- Butter
- Fat that adds richness and a tender texture to the filling.
- Sugar
- Adds sweetness and, creamed with butter, traps air that lightens the mixture.
- Lemon
- Juice provides acidity and the rind adds bright aroma.
- Pie crusts
- Enclose the filling and give the pie its structure and golden browning.
The step that matters
Fold in the beaten egg whites gently. The whites hold air that gives the filling lightness. Stirring hard or briskly deflates that foam, leaving a dense, flat pie after baking.
Swap the lemon
How well each one fits the dish's main ingredients (egg, butter, sugar):
- Vanillafits better
- Lemonthe original
- Raisinfits about as well
- Figfits about as well
Fit is the average pairing score against egg, butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
