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 Pie
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the filling
Dissolve corn starch in a little cold water.
Bring 1 cup of hot water to a boil.
Beat the egg yolks and egg white together.
Add sugar, butter, and grated lemon to the egg mixture.
Combine with the boiling water.
Bake the pie
Line a pie tin with the crust.
Pour the mixture into the crust and bake at 350°F (175°C).
Make and brown the meringue
Beat the egg whites until stiff, then gradually add 4 tablespoons of sugar.
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
- Egg yolks
- Thicken and enrich the filling as they set during baking.
- Corn starch
- Thickens the lemon filling so it holds a sliceable structure when cooled.
- Sugar
- Sweetens the filling and helps stabilize the whipped meringue.
- Lemon
- Adds tart acidity and aromatic citrus flavour to the filling.
- Butter
- Adds fat for richness and a smoother, softer texture in the filling.
- Egg whites
- Whipped into foam, they give the meringue its light, stable structure.
The step that matters
Combine with the boiling water. Eggs can scramble when hot liquid is added too quickly. The starch must also reach a boil to thicken fully, so the filling sets properly in the oven.

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