Why it works: Lemon and biscuit match in chemistry and in kitchens. They rank in the top 12% of all ingredient pairs, and cooks put them together in 697 recipes. Both carry nonanal, which smells fat, citrus. The science ↓
Lemon Cheese Cake Mixture
Ingredients
Directions
Prepare
Rub the sugar on the lemons to extract the flavor from the rind.
Make the custard
In an enamel saucepan, combine the butter, sugar, lemon juice, and eggs.
Place the saucepan over low heat and stir continuously in one direction until the mixture thickens to a custard-like consistency.
Add the biscuits or cake crumbs to prevent boiling over while cooking.
Store
Once cooked, transfer the mixture to dry jam jars and cover when cool.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and a smooth, silky texture to the custard.
- Eggs
- Thicken the mixture as they cook, setting it into a custard.
- Sugar
- Sweetens the custard and helps draw flavor from the lemon rind.
- Lemon juice
- Adds acidity that balances the sweetness and brightens the flavor.
The step that matters
Stirring over low heat. Eggs can scramble if the mixture gets too hot or is heated unevenly. Low heat and constant stirring let the eggs thicken gently into a smooth custard.
