Why it works: Barley and leek match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 142 recipes. Both carry 1-octen-3-ol, which smells mushroom, earthy. The science ↓
Mutton Soup
Ingredients
Directions
Prepare
Cut the mutton into 4 or 5 pieces and wash in cold water.
Place the mutton in a soup kettle and cover with cold water.
Simmer
Bring to a boil, skimming off any foam that rises to the surface.
Cover and simmer slowly for 5 hours.
After 3 hours, add the washed barley and let it boil for 2 hours.
Then add the celery, parsley, and leek.
Finish and serve
Once done, remove the meat and bones, skim the soup, and season with salt and pepper to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leg of old mutton
- Provides the meat and rich flavour that build the body of the broth as it simmers.
- Barley
- Releases starch during long boiling, thickening the soup and giving it a fuller texture.
- Leek
- Adds a mild onion-like sweetness and aroma to the broth.
- Celery
- Contributes a fresh, savoury aroma that rounds out the broth.
The step that matters
Skimming the foam after the boil begins. Foam carries impurities and coagulated proteins from the meat. Removing it early keeps the broth clear and clean-tasting rather than cloudy or greasy.
Swap the parsley
How well each one fits the dish's main ingredients (mutton, barley, celery, leek, pepper):
- Thymefits about as well
- Parsleythe original
- Marjoramfits less well
- Turmericfits less well
Fit is the average pairing score against mutton, barley, celery, leek, pepper. Candidates are from the same food group and used in at least 100 recipes.
