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 Pie with Milk
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
In a bowl, stir together butter, sugar, and egg yolks until very light.
Mix in the milk and flour until smooth.
Add the lemon juice and beat all together.
Pour the mixture into a pie crust and bake until set.
Top and brown
Beat the egg whites to a stiff froth and spread on top of the pie.
Return the pie to the oven and brown lightly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Add richness and help thicken the custard as it sets.
- Egg whites
- Whipped to a stiff froth, they form a light topping that browns in the oven.
- Sugar
- Sweetens the filling and helps the yolks become light and airy when creamed with butter.
- Lemon juice
- Adds acidity and bright flavor that balances the sweetness.
- Flour
- Thickens the milk mixture so the filling sets smoothly.
- Milk
- Provides moisture and body to the custard filling.
The step that matters
Beat the egg whites to a stiff froth. Egg whites must be whipped until stiff enough to hold their shape and spread over the pie. Under-whipped whites will slump and may not brown well, while the protein structure set by whipping gives the topping its light texture.
