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

What each ingredient does

Potatoes
Their starch breaks down during boiling and thickens the soup, giving it body.
Milk
Adds fat and milk proteins that make the soup richer and creamier.

The step that matters

Adding the milk before the long boil. Milk can scorch on the bottom of the pot or separate and curdle if it is boiled hard for a long time. Keep the heat gentle once the milk is in, and stir often to protect the soup's texture.

Swap the potato

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

  1. Capsicumfits better
  2. Potatothe original
  3. Tomatofits less well
  4. Carrotfits less well

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

“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
