Why it works: Corn and lemon are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 1,927 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Lemon Meringue Pie
Ingredients
Directions
Make the filling
Mix 1/2 cup water and corn starch to create a paste.
In a double boiler, combine 1 1/2 cups water and sugar; bring to a boil over direct heat.
Add the cornstarch paste and cook until the mixture thickens, about 15 minutes.
Pour the mixture over the slightly beaten egg yolks; return to the double boiler and cook for 1 more minute.
Stir in the lemon rind, lemon juice, and butter until well blended.
Cool the filling and pour it into the baked pie shell.
Make the meringue and finish
For the meringue, beat 3 egg whites until soft peaks form, then gradually add 9 tablespoons sugar and 1 teaspoon lemon juice until stiff peaks form.
Spread the meringue over the pie filling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Corn starch
- Thickens the filling into a sliceable custard as it cooks with the liquid.
- Egg yolks
- Enrich and thicken the filling, giving it a rich, set texture.
- Egg whites
- Whipped into foam to form the airy, stable meringue topping.
- Sugar
- Sweetens the filling and, in the meringue, stabilizes the whipped egg white foam.
- Lemon
- Supplies the bright acidity and aroma that define the filling's flavor.
The step that matters
Pour the cornstarch mixture over the egg yolks and cook only one minute more. Egg yolks can curdle or scramble if overheated, and cornstarch needs to reach a boil to reach full thickness. Returning the mixture to the double boiler gently cooks the yolks while keeping the filling smooth.
