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

What each ingredient does

Tripe
Forms the main chewy body of the soup after boiling until tender.
Bacon
Adds fat and savory smoky flavor from rendered drippings.
Flour
Thickens the soup when cooked with butter and stirred in.
Butter
Adds richness and helps flour blend smoothly for thickening.

The step that matters

Mixing the flour with the butter until smooth. Flour clumps if added directly to hot liquid. Blending it with fat first coats the starch granules so they disperse evenly and thicken the soup without lumps.

Swap the tomato

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

  1. Chivefits better
  2. Leekfits better
  3. Shallotfits better
  4. Tomatothe original

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