Why it works: Butter and lemon are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 41,227 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Chess Pie
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the filling
Cream together the sugar and butter.
Beat the yolks of the eggs until light and stir into the cream mixture.
Add the lemon juice and half of the grated lemon peel, then whip for 2 minutes.
Fill the puff pastry crusts with the mixture and bake at 400°F (200°C).
Top and brown
For the meringue, beat the egg whites until stiff and gradually add the sugar.
Spread the meringue over the pie and brown quickly 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
- Thicken the filling as they set, giving the pie a rich, custard-like body.
- Butter
- Adds fat for richness and a tender, smooth texture in the filling.
- Sugar
- Sweetens the filling and helps create a crisp, browned meringue topping.
- Lemon juice
- Adds acidity that balances the sweetness and brightens the flavour.
- Egg whites
- Whipped into a stiff foam that forms the meringue topping and browns in the oven.
The step that matters
Browning the meringue. Meringue must be spread so it touches the edges and browned quickly; overbaking can toughen or weep it, while underbaking leaves it soft and pale.
Swap the lemon

Fit is the average pairing score against sugar, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
