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 ↓

In a saucepan, add the butter and boiling water.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Corn starch
- Thickens the lemon filling as it heats, giving it a sliceable set.
- Egg yolks
- Enrich and thicken the filling, adding richness and body.
- Egg whites
- Whip into a foam that forms the light, airy meringue topping.
- Sugar
- Sweetens the filling and helps stabilise the whipped meringue.
- Lemon juice
- Adds acidity that brightens the filling and balances the sweetness.
The step that matters
Bake the filling until set. Starch thickens only when the mixture reaches a full simmer or near-boil and holds it; underbaked filling stays runny and will weep or slump when cut.
Swap the lemon

- Figfits about as well
- Lemonthe original
Fit is the average pairing score against corn, butter, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
