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

What each ingredient does

Mutton
Provides the meat and rich flavour that forms the body of the broth.
Barley
Releases starch as it simmers, thickening the broth and giving it body.
Flour
Cooked with butter into a roux, it thickens the soup smoothly.
Butter
Forms a roux with flour and adds richness to the thickened broth.

The step that matters

Cooking the roux until smooth. Flour must be cooked with butter before it goes into the liquid; otherwise it clumps and tastes raw. Stirring it in smoothly lets it thicken the soup evenly.

Swap the onion

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

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

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