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.
Bake until golden.
Make the filling
In a bowl, beat the egg yolks with sugar, salt, lemon juice, and lemon rind.
Mix corn starch with melted butter and stir into boiling milk.
Cook for 1 minute.
Let the milk mixture cool.
Pour it slowly over the egg mixture and stir well.
Pour the combined mixture into the baked crust.
Bake for 15 minutes.
Top and serve
Beat the egg whites with sugar and a pinch of salt until frothy.
Spread the meringue over the pie.
Return to the oven to brown for a few minutes.
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 filling so it sets and holds its shape when cut.
- Lemon juice
- Adds the sharp acidity that balances the sweetness of the filling.
- Egg whites
- Whip into a foam that forms the light, sweet meringue topping.
- Sugar
- Sweetens the filling and helps stabilize the whipped egg white meringue.
- Butter
- Adds fat and a smooth, rich mouthfeel to the filling.
The step that matters
Cooling the milk mixture before adding the yolks. Pouring hot starch mixture onto raw egg yolks can scramble them. Letting the milk cool first keeps the yolks smooth and lets the filling thicken evenly.
Swap the lemon
