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 and acidic, sweet tomato flavor of the bisque.
Sweet milk
Adds richness and creamy body, softening the acidity of the tomatoes.
Flour
Thickens the soup as its starch gelatinizes in the hot liquid, giving a smooth texture.

The step that matters

Stirring the flour paste into the boiling tomatoes. Flour mixed with liquid first into a smooth paste, then added to hot liquid, disperses evenly. Lumps form if flour is dumped in dry or added to cool liquid, and the starch then thickens unevenly.

Swap the tomato

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

  1. Capsicumfits better
  2. Arrowrootfits better
  3. Potatofits better
  4. Tomatothe original

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