Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Neck of mutton
Provides the meat and bone flavour that gives the broth its body.
Barley
Releases starch as it simmers, thickening the broth and adding a chewy texture.
Flour
Cooked with butter, it thickens the soup and keeps it smooth.
Butter
Adds richness and carries flavour into the flour thickener.
Turnip
Softens during simmering, adding sweetness and body to the broth.
Carrot
Softens during simmering, adding gentle sweetness to the broth.

The step that matters

Cooking the flour and butter until smooth. Flour added straight to hot liquid clumps. Cooking it first with butter coats the starch granules so they disperse evenly and thicken the soup without lumps.

Swap the onion

How well each one fits the dish's main ingredients (mutton, turnip, carrot, celery, barley, flour, butter):

  1. Leekfits better
  2. Parsnipfits better
  3. Beetrootfits better
  4. Onionthe original

Fit is the average pairing score against mutton, turnip, carrot, celery, barley, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
