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

What each ingredient does

Corn
Provides the main body and natural sweetness of the soup.
Milk
Forms the creamy liquid base that the soup is built on.
Flour
Thickens the milk mixture so the soup has body.
Butter
Adds fat and richness, carrying flavor through the soup.
Onion
Adds a savory aroma and depth when cooked until light brown.
Egg yolk
Enriches and thickens the soup, giving it a smoother, richer texture.

The step that matters

Pour the hot soup slowly over the egg yolk. Adding hot soup gradually warms the yolk gently so it blends in smoothly. Pouring too fast or without stirring can cause the egg to scramble into small cooked bits.

Swap the white pepper

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

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

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