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 ↓
Broths, Gravies, and Soups
Ingredients
Directions
Make the soup
In a stewpan, add boiling water and simmer gently for 2 hours.
Cut the meat into mouthful pieces and add to the soup.
Cut the cow heel into 1-inch pieces and add to the soup.
Thicken and season
In a separate stewpan, mix thickening with a ladleful of gravy until well combined.
Pour the mixture back into the stewpan and simmer for another 30 minutes.
Strain the soup through a fine sieve into a larger stewpan.
Squeeze the juice of the lemon into the soup.
Add browning, mushroom ketchup, salt, pepper, nutmeg, and wine.
Simmer all ingredients together for about 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gravy beef
- Breaks down during long simmering to give the broth its meaty body and flavour.
- Cow heel
- Releases gelatin into the broth during long simmering, giving body and a rich mouthfeel.
- Thickening (no. 47)
- Starch that swells when heated, thickening the broth to a richer consistency.
- Madeira or sherry wine
- Adds acidity and aromatic depth that brightens the savoury broth.
The step that matters
Thickening the broth. Starch must be mixed smoothly with a little cold or warm liquid before being returned to the pot, otherwise it clumps. Simmering then lets the starch swell and thicken the soup evenly.
Swap the lemon
How well each one fits the dish's main ingredients (beef, mushroom, ketchup, pepper, nutmeg, sherry):
- Lemonthe original
- Limefits about as well
- Orangefits less well
- Grapefits less well
Fit is the average pairing score against beef, mushroom, ketchup, pepper, nutmeg, sherry. Candidates are from the same food group and used in at least 100 recipes.
