Why it works: Onion and chicken are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 17,814 recipes. Both carry gamma-nonanolactone, which smells coconut, sweet. The science ↓
Cheap Broth
Ingredients
Directions
Prepare
Wash the sheep's head thoroughly.
Boil it in plenty of water for 10 minutes with 1 tablespoon of salt. Discard the water.
Make the broth
Combine the head, cut-up meat, onions, peppercorns, groats, barley, and 1 gallon of cold water in a large pot.
Bring the mixture to a boil and skim the surface.
Cover tightly and simmer gently for 6 hours, adding water as needed to maintain the original quantity.
Strain the broth.
Finish and serve
Rub the onions, barley, and groats through a sieve.
Remove the fat from the broth.
Add the thickened mixture and boil together.
Serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pearl barley
- Its starch thickens the broth as it cooks and is rubbed through a sieve.
- Groats
- Their starch thickens the broth, and they are rubbed through a sieve to add body.
- Onions
- They add savory sweetness and flavor to the broth, and are rubbed through to thicken it.
- Sheep's head
- Its bones, skin and connective tissue release gelatin and rich flavor during long simmering.
The step that matters
Simmer gently with the lid on. A gentle simmer keeps the broth clear and lets collagen slowly release gelatin without breaking the meat apart. Boiling hard makes it cloudy and greasy, and topping up water keeps the volume steady for a proper body.
Swap the onion
How well each one fits the dish's main ingredients (mutton, chicken, barley):
- Leekfits better
- Potatofits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against mutton, chicken, barley. Candidates are from the same food group and used in at least 100 recipes.
