Why it works: Lemon and butter 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 ↓

Ingredients
Directions
The book says “a cool oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Prepare
Grate the crumb of a roll and finely grate the rind of half a lemon.
Make the filling
Add sugar, butter, lemon juice, beaten egg yolks, and beaten egg whites.
Set the mixture over low heat and stir until thickened.
Bake
Pour into a flat dish lined with puff pastry.
Bake in a moderate oven (350°F / 175°C) for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks and whites thicken the filling and help it set into a custard-like texture.
- Butter
- Adds richness and a soft, tender mouthfeel to the filling.
- Fine sugar
- Sweetens the filling and helps give it a smooth, glossy texture.
- Roll crumb
- Bulks up the filling and gives it body as it absorbs the liquid ingredients.
- Lemon juice
- Adds acidity and bright flavour that balances the sweetness.
The step that matters
Stirring over low heat until thickened. Egg proteins begin to set around 70°C, so gentle low heat with constant stirring thickens the mixture smoothly; higher heat can scramble the eggs into lumps.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, butter, egg):
- Vanillafits better
- Lemonthe original
- Raisinfits about as well
- Figfits about as well
Fit is the average pairing score against sugar, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
