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 ↓
Mrs. Tirrell's 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.
Make the filling
Mix lemon juice, grated rind, egg yolks, sugar, and corn starch made smooth in a little cold water.
Pour in boiling water, let cool, then add salt.
Line a deep pie plate with pastry and pour in the lemon mixture.
Bake in a 350°F (175°C) oven until set.
Top with meringue
Beat egg whites with fine sugar until soft peaks form.
Spread the meringue over the baked pie and brown lightly in the oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Enrich and thicken the filling, adding richness and a smooth set.
- Corn starch
- Thickens the lemon mixture as it heats, giving the filling body.
- Lemon juice
- Provides acidity and bright flavour that balances the sugar.
- Egg whites
- Whip into a foam that forms the meringue topping and gives lift.
- Sugar
- Sweetens the filling and helps stabilise the whipped egg white meringue.
The step that matters
Beat the egg whites until soft peaks form. Egg whites must be whipped to a stable foam before spreading. Under-beaten whites stay runny and may weep, while over-beaten whites turn dry and grainy, so the meringue may not hold its shape or brown well.
