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

What each ingredient does

Canned tomato
Provides the main body and tomato flavor of the soup.
Milk
Adds creaminess and mild sweetness, softening the tomato's acidity.
Corn starch
Thickens the milk so the finished bisque has a smooth, velvety body.
Butter
Adds richness and a silky mouthfeel to the finished soup.

The step that matters

Thickening the milk with corn starch. Corn starch must be mixed into the milk and heated so the starch granules swell and gelatinize. If lumps form or it isn't heated enough, the bisque stays thin or grainy.

Swap the tomato

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

  1. Capsicumfits better
  2. Potatofits better
  3. Sweet potatofits about as well
  4. Tomatothe original

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