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

What each ingredient does

Milk
Forms the creamy liquid base of the soup.
Mashed potatoes
Thicken the soup and give it body and a smooth texture.
Onion
Adds savory aroma and mild sweetness as it softens in the liquid.
Butter
Adds richness and fat for a smoother mouthfeel.

The step that matters

Heat until hot but not boiling. Milk-based soups can scorch or curdle and separate if they boil, so gentle heating keeps the texture smooth.

Swap the onion

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

  1. Capsicumfits better
  2. Asparagusfits about as well
  3. Tomatofits about as well
  4. Onionthe original

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