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 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 filling
Roll the lemon and squeeze the juice over half of the sugar.
Beat the egg yolks and mix in the lemon juice, butter, and milk.
Pour the mixture into a pie crust and bake in a 350°F (175°C) oven.
Make and brown the meringue
Beat the egg whites with the remaining sugar until stiff peaks form.
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 the egg whites hold stiff peaks in the meringue.
- Lemon
- Provides the acidity and aroma that give the filling its tart flavor.
- Milk
- Adds moisture and richness to the filling.
The step that matters
Beating the egg whites to stiff peaks. Whites must be whipped until stiff and the sugar fully dissolved, or the meringue will weep or collapse. Browning it in the oven then sets the topping.
