Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sheep's head
- Forms the main body of the broth, releasing collagen and flavour as it simmers slowly.
- Barley
- Thickens the broth as its starch releases during long simmering, giving body.
- Peas
- Break down during cooking, adding earthy sweetness and thickening the liquid slightly.
- Onions
- Soften and sweeten during simmering, adding savoury depth to the broth.
The step that matters
Boil slowly for three hours. A gentle simmer keeps the broth clear and lets collagen and connective tissue break down into tender meat. A hard boil makes the liquid cloudy and can toughen the meat.
Swap the peas
How well each one fits the dish's main ingredients (barley, onion, carrot, turnip, parsley):
- Lentilsfits better
- Beansfits better
- Chickpeafits better
- Peasthe original
Fit is the average pairing score against barley, onion, carrot, turnip, parsley. Candidates are from the same food group and used in at least 100 recipes.
