Why it works: Lemon and corn 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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Prepare a pie crust and place it in a pie plate.
In a bowl, beat the eggs and corn starch together until well combined.
Make and bake the pie
Add the lemon juice, lemon rind, sugar, and cold water to the egg mixture and stir quickly.
Pour the mixture into the prepared crust.
Cover the filling with the crust, either fully or in strips.
Bake for 30-35 minutes or until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the filling into a custard as they cook, giving it body and structure.
- Corn starch
- Thickens the liquid filling so it holds its shape when cut.
- Sugar
- Sweetens the filling and balances the sharpness of the lemon.
- Lemon juice
- Adds acidity and bright lemon flavour to the filling.
- Lemon rind
- Adds aromatic lemon oils that give the filling its fragrance.
The step that matters
Stir the filling quickly after adding the liquids. Corn starch must be evenly dispersed before heating or it can clump and leave lumps or uneven thickening. Quick stirring keeps the starch suspended in the liquid so the filling sets smoothly once baked.
