Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Lemon Cream 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.
Make the filling
Preheat the oven to 350°F (175°C).
In a bowl, beat the egg yolks and add the sugar, milk, and butter. Mix well.
Extract the juice of the lemon and grate the rind. Add both to the mixture.
Thicken the mixture with cornstarch and pour it into a pie crust.
Bake until set.
Top and finish
In another bowl, beat the egg whites until soft peaks form, then gradually add powdered sugar.
Spread the meringue over the pie and bake until lightly browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the filling and add richness and a smooth, custard-like texture.
- Egg whites
- Whip into a foam that forms the meringue topping and browns in the oven.
- Cornstarch
- Thickens the lemon filling so it sets firmly when cooled.
- Lemon
- Provides the sharp acidity and bright aroma that define the pie.
- Sugar
- Sweetens the filling and balances the lemon's acidity.
- Butter
- Adds fat for richness and a smoother, softer filling texture.
The step that matters
Thicken the mixture with cornstarch. Cornstarch must be fully mixed and heated until the filling thickens; if it is undercooked, the starch will not set and the filling will stay runny after cooling.
