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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Corn starch
- Thickens the boiling water into a set, sliceable filling.
- Egg yolks
- Enrich the filling and help it set as it bakes.
- Egg whites
- Form a light topping that browns in the oven.
- Sugar
- Sweetens the filling and balances the lemon's tartness.
- Lemon juice and rind
- Provide the sharp, aromatic lemon flavor and acidity.
The step that matters
Spread beaten egg whites on top and return to the oven to brown. Egg whites must be fully beaten and spread over the filling so they seal the surface. Browning depends on the oven heat reaching the meringue-style topping, so watch it closely to avoid over-browning.
