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

What each ingredient does

Calf's head
Supplies gelatinous connective tissue that gives the finished soup body and a rich mouthfeel.
Beef
Adds savoury meaty depth to the broth during the long gentle stew.
Calf's foot
Releases gelatin into the broth, adding body and a silky texture.
Flour
Thickens the broth as its starch swells with heat.
Egg yolks
Enrich and further thicken the soup, adding richness and smoothness when gently heated.
Sherry wine
Adds acidity and aromatic depth to the finished soup.

The step that matters

Stir over gentle heat until nearly boiling. Egg yolks thicken by coagulating when heated; if the soup boils after they are added, they can curdle and turn grainy, so heat must stay gentle.

Swap the clove

How well each one fits the dish's main ingredients (beef, ham, onion, turnip, carrot, celery, pepper):

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

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