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
Place the mutton in a stewpan with water and bring to a boil.
Add Scotch barley, leeks, onions, parsley, and thyme.
Skim the surface, then reduce heat and simmer for 2 hours.
Skim again and add boiling water if the broth is too thick.
Add the vegetables and serve
Add turnips, celery, and carrots, then simmer for another 1.5 hours.
The barley should be almost 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
- Neck of mutton
- Gives the broth its meaty flavour and body as it simmers.
- Scotch barley
- Thickens the broth and softens until it is almost dissolved.
- Leeks
- Add a mild onion-like sweetness that rounds out the broth.
- Onions
- Add savoury sweetness and aroma to the broth base.
- Turnips
- Soften during simmering and add a mild, slightly sweet flavour.
- Carrots
- Add gentle sweetness and colour to the broth.
The step that matters
Skimming the surface. Skimming removes foam and loose fat that would otherwise cloud the broth and taste greasy. Doing it at the start and again after the simmer keeps the broth clear and clean-flavoured.
