Why it works: Rice and barley match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 568 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Sheep’s Head Broth
Ingredients
Directions
Prepare
Wash and soak the sheep's head, then split it and remove the brains.
Make the broth
In a large pot, bring the head and cold water to a boil, adding a little salt.
Skim off any impurities, then add the vegetables and parsley.
Add the washed and soaked rice and barley, and boil until everything is perfectly tender.
Serve
Serve the head separately, along with some of the vegetables.

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 main meat and rich, gelatinous body to the broth as it simmers.
- Broken rice
- Thickens the broth slightly and adds body as its starch releases during boiling.
- Pearl barley
- Softens during long boiling and adds body and a chewy texture to the broth.
The step that matters
Skimming impurities. Foam and scum rising during the first boil can make the broth cloudy and off-flavoured, so they should be removed before the vegetables and grains go in.
Swap the parsley
How well each one fits the dish's main ingredients (rice, barley):
- Cinnamonfits better
- Turmericfits better
- Celeryfits better
- Parsleythe original
Fit is the average pairing score against rice, barley. Candidates are from the same food group and used in at least 100 recipes.
