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

What each ingredient does

Tomatoes
Provide the main body, acidity and flavour of the soup.
Flour
Thickens the soup as it mixes with butter and liquid.
Butter
Carries the flour so it blends smoothly into the soup without lumps.
Chicken
Flavours the broth and adds savoury richness.
Bacon
Adds smoky, savoury fat that flavours the broth.

The step that matters

Stirring the flour and butter mixture back into the pot. Flour added directly to hot liquid clumps. Mixing it first with butter and some soup thins it so it disperses evenly and thickens smoothly.

Flavor stand-ins for the onion

How well each one fits the dish's main ingredients (chicken, tomato, sugar, pepper, flour, butter):

  2. Potatobetter flavor fit
  3. Okrabetter flavor fit
  4. Onionthe original

Fit is the average pairing score against chicken, tomato, sugar, pepper, flour, butter. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
