Why it works: Corn and milk 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 ↓
Delicious 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.
Make the filling
Preheat the oven to 350°F (175°C).
Beat the yolks of 3 eggs until light.
Mix 2 tablespoons of corn starch in a little milk.
Add 1 cup of sugar, the juice of 1 lemon, and a little grated peel.
Stir in 1 large cup of milk and beat all together.
Pour the mixture into a pie crust and bake until set.
Make the meringue and finish
Beat the whites of the eggs to a stiff froth.
Add 2 tablespoons of sugar to the egg whites and spread evenly over the pie.
Return the pie to the oven until the meringue is slightly brown.

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Enrich the filling and help it thicken into a rich custard when heated.
- Corn starch
- Thickens the milk and lemon mixture as it heats, giving the filling a sliceable body.
- Egg whites
- Whip into a foam that gives the meringue its light, airy structure.
- Lemon juice
- Adds acidity that brightens the filling and balances its sweetness.
- Sugar
- Sweetens the filling and, in the meringue, helps stabilize the whipped whites.
- Milk
- Provides moisture and body to the filling.
The step that matters
Bake the filling until set. Cornstarch only thickens fully once the mixture is heated enough for its starch granules to swell. Underbaked filling stays loose and runs when sliced.

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