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 ↓
Lemon Cheesecakes
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the lemon filling
Combine sugar, butter, lemon rind, and strained lemon juice in a saucepan; stir until sugar dissolves.
Beat egg yolks and add to mixture; stir and cook slowly until thickened.
Let mixture cool in a dry place until needed.
Bake and serve
Line patty pans with short paste and fill them three-quarters full with the lemon mixture.
Add a few strips of candied peel on top and bake for about 20 minutes at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks thicken the lemon mixture as they cook and set it into a custard.
- Butter
- Adds richness and a smooth, silky texture to the lemon filling.
- Loaf sugar
- Sweetens the filling and balances the sharp acidity of the lemon juice.
- Lemon juice
- Provides the tart flavour and acidity that gives the filling its character.
The step that matters
Cook the filling slowly until thickened. Egg yolks thicken when heated gently; too much heat can curdle them into lumps, while too little leaves the filling runny.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, butter, egg):
- Vanillafits better
- Lemonthe original

- 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.
