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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal knuckle
- Provides meat and gelatin, giving body and a rich, savoury flavour to the soup.
- Madeira wine
- Adds acidity and aromatic sweetness that deepens the flavour of the broth.
- Cow heels
- Release gelatin during long cooking, adding body and a silky texture to the soup.
- Egg yolks
- Thicken the mixture through gentle heat and add richness and smoothness.
The step that matters
Thicken the mixture with the egg yolks. Egg yolks set when heated, so they must be added gently and off a rolling boil. Too much heat makes them scramble into grainy lumps instead of thickening the soup smoothly.
Swap the mace
How well each one fits the dish's main ingredients (veal, pepper, madeira wine, egg, meat, lemon):
- Parsleyfits better
- Thymefits better
- Marjoramfits better
- Macethe original
Fit is the average pairing score against veal, pepper, madeira wine, egg, meat, lemon. Candidates are from the same food group and used in at least 100 recipes.
