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

What each ingredient does

Onions
Soften and build a sweet, aromatic base for the soup.
Butter
Carries the aromatics and adds richness to the soup.
All-purpose flour
Thickens the soup slightly as it cooks with the butter.
Tomatoes
Provide the main body, acidity and flavour of the soup.
Corn
Adds sweetness and body to the soup.
Egg yolks
Enrich the soup and give it a smooth, creamy texture when stirred in.

The step that matters

Stir the egg yolks and cream into the soup. Egg yolks can curdle if they get too hot. Mixing them with cream first and stirring them into the soup off the heat, rather than boiling after adding them, helps keep the soup smooth.

Swap the white pepper

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

  1. Cinnamonfits better
  2. Capersfits better
  3. Jalapenofits better
  4. White pepperthe original

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