Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shin of beef or ox-cheek
- Provides meat that becomes tender and flavourful during long, slow simmering.
- Barley
- Thickens the broth slightly as its starch releases during simmering and adds chewy texture.
- Onions
- Add sweetness and savoury depth to the broth as they soften and release their flavour.
The step that matters
Simmer gently after boiling. A rolling boil toughens meat proteins and can make the broth cloudy, so the heat should be lowered to a gentle simmer for the several hours needed to tenderise the beef.
Swap the potato
The recipe marks potato as optional. How well each one fits the dish's main ingredients (beef, barley, parsley, onion):
