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

What each ingredient does

Pearl barley
Swells as it cooks, giving the soup body and a chewy texture.
Butter
Enriches the soup and carries the carrot's flavor when the carrot is stewed.
Flour
Mixed with butter and stirred in to thicken the soup.
Carrot
Stewed slowly in butter to soften and add sweetness to the soup.

The step that matters

Add the flour-butter mixture to the soup. Flour must be cooked in fat before or as it meets liquid, or it forms lumps and thickens unevenly. Keep the soup boiling after adding it so the starch swells fully and the flour taste cooks out.

Swap the carrot

How well each one fits the dish's main ingredients (meat, barley, butter, flour):

  1. Leekfits better
  2. Shallotfits better
  3. Asparagusfits better
  4. Carrotthe original

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