Why it works: Turnip and leek 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 ↓
Sheep's Head and Barley Broth
Ingredients
Directions
Place the sheep's heads in a 3-gallon pot and fill it nearly full with cold water.
Set the pot on the fire to boil, skimming off any scum that rises.
Add the chopped carrots, turnips, leeks, onions, celery, thyme, black pepper, coarse sea salt, and barley.
Allow the mixture to boil gently for at least 3 hours until the soup is cooked.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sheep's heads
- Provide the meat and rich gelatin that give the broth its body and savoury depth.
- Barley
- Thickens the broth as its starch swells and softens during long simmering.
- Carrots
- Add natural sweetness and body to the broth as they soften.
- Turnips
- Contribute mild sweetness and soft texture as they cook down into the broth.
The step that matters
Skimming the scum. Foam rising during the first boil carries impurities that can make the broth cloudy and off-flavoured, so it should be removed as it forms.
Swap the onion
How well each one fits the dish's main ingredients (carrot, turnip, leek, celery, thyme, pepper, barley):
- Parsnipfits better
- Lettucefits better
- Beetrootfits better
- Onionthe original
Fit is the average pairing score against carrot, turnip, leek, celery, thyme, pepper, barley. Candidates are from the same food group and used in at least 100 recipes.
