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

What each ingredient does

Potatoes
Form the body of the soup, as their starch thickens it when cooked and mashed.
Butter
Adds fat for richness and a smooth, rounded mouthfeel.
Milk
Adds creaminess and liquid, giving the soup its smooth, mellow body.

The step that matters

Boil for 2 to 3 minutes. Milk contains sugars and proteins that scorch easily on the bottom of a pan. Keep the heat controlled and stir so the soup does not burn or boil over.

Swap the white pepper

How well each one fits the dish's main ingredients (potato, butter, milk, parsley, onion, mace):

  1. Thymefits better
  2. Nutmegfits better
  3. Marjoramfits better
  4. White pepperthe original

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