Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide the whites that hold the filling and the rich yolks that form the paste.
- Butter
- Adds fat and richness, making the yolk mixture smoother and creamier.
- Lemon juice
- Adds acidity that brightens the rich yolk filling and balances its flavour.
The step that matters
Work the yolks into a paste. Yolks must be mashed fully smooth before filling; lumps leave pockets of dry yolk and an uneven texture. Adding the butter or oil first helps the mixture blend into a creamy paste.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
