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

What each ingredient does

Flour
Thickens the broth into a lightly body-rich soup as its starch swells when heated.
Eggs
Set in the hot soup to add richness and body to the broth.
Ham broth
Provides the main savory flavor and liquid base of the soup.

The step that matters

Gradually stir in the flour mixed with cold broth. Flour added directly to hot liquid clumps, because its starch grains hydrate unevenly. Mixing it with cold broth first and adding it slowly keeps the soup smooth as it thickens.

Swap the parsley

How well each one fits the dish's main ingredients (ham, flour, egg):

  1. Capersfits better
  2. Nutmegfits better
  3. Jalapenofits better
  4. Parsleythe original

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