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

What each ingredient does

Canned tomatoes
Provide the main body and flavor of the soup.
Milk
Forms the creamy base that gives the bisque its smooth body.
Stale bread crumbs
Thicken the milk slightly and add body to the soup.
Baking soda
Neutralizes the tomatoes' acidity, mellowing their sharpness and softening flavor.
Sugar
Balances the acidity of the tomatoes with sweetness.
Butter
Adds richness and a silky mouthfeel to the finished soup.

The step that matters

Add baking soda to the tomatoes. Baking soda reacts with acid and releases carbon dioxide, so adding too much can cause foaming and a soapy, off flavor. Measure it carefully, since the amount is small.

Swap the onion

How well each one fits the dish's main ingredients (tomato, sugar, clove, bread, milk, pepper, butter):

  1. Capsicumfits better
  2. Potatofits better
  3. Carrotfits better
  4. Onionthe original

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