Why it works: Turnip and arrowroot share more aroma than cooks usually use. They rank in the top 1% of all ingredient pairs, and cooks put them together in 64 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Sheep's Head Broth
Ingredients
Directions
Prepare the head
Scald the sheep's head in hot water and scrape off all the hair with a sharp knife.
Divide the head like a calf's head and place it in a saucepan with enough water to cover it.
Add the onions, vinegar, and salt.
Remove the scum as it rises.
Once boiling, reduce to a simmer until the head is thoroughly cooked.
Make the soup
Cool the broth, remove all the fat, and strain it.
Return the broth to the heat.
Add a quartered onion, sliced carrot, small turnip, and parsley.
When it boils, sprinkle in the rice or pearl barley and season to taste.
Let the soup stew until the rice or barley is cooked.
For a thicker soup, add arrowroot or mashed potato.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sheep's head
- Provides the meat and bones that build the broth's body and flavour.
- Rice or pearl barley
- Absorbs liquid and swells during stewing, giving the soup body and substance.
- Turnips
- Soften during simmering and add a mild, slightly sweet vegetable flavour.
- Carrot
- Adds gentle sweetness and colour as it softens in the broth.
- Arrowroot or mashed potato
- Thickens the broth by binding water when heated.
The step that matters
Removing the scum and fat. Scum rising during boiling and fat left in the cooled broth can make the soup cloudy and greasy. Skimming as it rises and chilling the broth before straining keeps the broth clear and clean-tasting.
Swap the arrowroot
The recipe marks arrowroot as optional. How well each one fits the dish's main ingredients (onion, vinegar, turnip, carrot, parsley, rice):
- Leekfits better
- Parsnipfits better
- Okrafits better
- Arrowrootthe original
Fit is the average pairing score against onion, vinegar, turnip, carrot, parsley, rice. Candidates are from the same food group and used in at least 100 recipes.
