Why it works: Milk and corn are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 6,955 recipes. Both carry hexanal, which smells green, grassy. 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
Preheat the oven to 350°F (175°C).
In a bowl, mix the lemon juice, lemon rind, sugar, milk, corn starch, and egg yolks until smooth.
Pour the mixture into two pie crusts.
Top and bake
In another bowl, beat the egg whites until frothy.
Add the powdered sugar to the egg whites and mix well.
Spread the egg white mixture over the pies.
Bake in the oven until the tops are 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 color to the custard.
- Egg whites
- Whip into a foam that bakes into a light, lightly browned topping.
- Corn starch
- Thickens the lemon filling as it heats, giving it a set, sliceable body.
- White sugar
- Sweetens the filling and balances the sharpness of the lemon juice.
- Lemon juice
- Provides the tart acidity that defines the flavor of the filling.
The step that matters
Beating the egg whites until frothy. Egg whites hold air only when fully whipped and free of grease or yolk; underwhipped or greasy whites will not form a stable foam that bakes into a light topping.
Swap the lemon

Fit is the average pairing score against sugar, milk, corn, egg. Candidates are from the same food group and used in at least 100 recipes.
