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

What each ingredient does

Beef
Long simmering breaks down connective tissue, making the broth rich and the meat tender.
Barley
Swells as it cooks, adding body and a chewy texture to the soup.
Flour
Mixed with water into a paste, it thickens the broth as it heats.
Butter
Adds fat that carries flavor and gives the soup a smoother mouthfeel.

The step that matters

Stirring in the flour paste. Flour added directly to hot liquid clumps and stays raw-tasting. Mixing it into cold water first to form a smooth paste lets it disperse evenly and thicken the soup without lumps.

Swap the clove

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

  1. Parsleyfits better
  2. Thymefits better
  3. Turmericfits better
  4. Clovethe original

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