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 Meringue 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
In a saucepan, boil the water and sugar together.
Add the corn starch moistened with a little cold water and cook for 5 minutes.
Stir in the egg yolks, lemon juice, lemon rind, and salt.
Cool slightly and pour into the pre-baked pie crust.
Top and bake
Make meringue by beating the egg whites with 2 tablespoons of sugar until stiff.
Spread the meringue over the pie filling.
Bake in a moderate oven at 350°F (175°C) until the meringue is set and lightly browned.

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Corn starch
- Thickens the filling as it cooks, giving it a set, sliceable body.
- Egg yolks
- Enrich and thicken the filling, adding richness and a smooth texture.
- Egg whites
- Whipped into a foam that forms the light, airy meringue topping.
- Lemon
- Provides the tart acidity and aroma that define the filling.
- Sugar
- Sweetens the filling and helps stabilise the whipped egg white meringue.
The step that matters
Beating the egg whites until stiff. Egg whites must be whipped until they hold firm peaks; under-whipped whites will weep and collapse, while the sugar added during beating helps stabilise the foam.
