Why it works: Pepper and lemon 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 ↓

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, carrying flavour through the sauce.
- Flour
- Thickens the sauce as it cooks with the water.
- Water
- Forms the liquid base that the flour thickens into a smooth sauce.
- Egg yolks
- Add richness and body, and thicken the sauce gently when heated.
The step that matters
Adding the egg yolks. Egg yolks thicken by coagulating when heated. If the sauce is too hot or boils after they go in, they can scramble and turn grainy. Keeping the heat gentle and the sauce just hot, not boiling, keeps it smooth.
