Why it works: Leek and turnip match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,046 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Scotch Mutton Broth
Ingredients
Directions
Make the broth
Combine mutton and water in a stewpan and bring to a boil.
Add Scotch barley, leeks, onions, parsley, and thyme, then skim the surface.
Reduce heat and simmer for 2 hours, skimming again.
If the broth is too thick, add ½ pint of boiling water.
Add vegetables and finish
Add turnips, celery, and carrots and simmer slowly for another 1.5 hours.
The barley should be almost fully dissolved.
Serve the meat with the broth or separately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Gives the broth its rich, savoury flavour and body as it simmers.
- Scotch barley
- Thickens the broth as its starch releases during long simmering.
- Leeks
- Add mild onion sweetness and aroma to the broth.
- Turnips
- Add sweetness and soft body after long, slow simmering.
- Carrots
- Add natural sweetness and colour to the broth.
The step that matters
Skimming the surface. Skimming removes the grey foam and fat that rise from the meat, keeping the broth clear and tasting clean rather than greasy or cloudy.
Swap the onion
