Why it works: Butter and milk 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 Meringue 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 crust
Preheat the oven to 350°F (175°C).
Line a medium pie pan with the pie crust and bake until lightly golden.
Make the filling
In a bowl, beat the egg yolks with 4 tablespoons of sugar, ¼ teaspoon salt, lemon juice, and grated lemon rind.
Mix the corn starch with melted butter, then stir into the boiling milk and cook for 1 minute.
Allow the milk mixture to cool, then slowly pour it over the egg mixture and stir to combine.
Pour the filling into the baked crust and bake for 15 minutes.
Top and serve
Meanwhile, beat the egg whites with 4 tablespoons of sugar and a tiny pinch of salt until frothy.
Spread the meringue over the pie filling and return to the oven to brown for a few minutes, being careful not to burn.
Serve cold.

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 to the custard.
- Corn starch
- Thickens the lemon custard so it sets when cooled.
- Lemon juice
- Provides the sharp acidity that defines the lemon filling.
- Egg whites
- Whip into a foam that forms the light, stable meringue topping.
- Sugar
- Sweetens the filling and helps stabilize the whipped meringue.
- Butter
- Adds richness and a smoother texture to the filling.
The step that matters
Cooling the milk mixture before adding the yolks. Pouring hot starch-thickened milk onto raw egg yolks can scramble the yolks. Letting the milk cool first lets the yolks blend in smoothly, and the filling sets as it chills.
