Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Its connective tissue breaks down into gelatin during slow cooking, giving the broth body and rich flavor.
- Scotch barley
- Releases starch as it cooks, thickening the broth and adding a chewy texture.
- Onion
- Softens and sweetens as it cooks, adding savory depth to the broth.
- Carrot
- Adds natural sweetness and color to the broth.
- Turnip
- Softens into the broth, adding earthy flavor and body.
- Leek
- Adds a mild, sweet onion-like aroma as it softens.
The step that matters
Cook gently for 2 hours. A gentle simmer lets collagen in the mutton convert slowly to gelatin while keeping the meat tender. Boiling hard toughens the meat and makes the broth cloudy.
Swap the onion
