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

What each ingredient does

Potatoes
Break down during cooking to thicken the soup and give it body.
Celery
Provides the main flavor and aroma of the soup.
Onions
Add sweetness and savory depth as they soften in the broth.
Milk
Adds creaminess and richness to the finished soup.

The step that matters

Bringing the milk to a boil. Milk can scorch on the bottom of the pot and form a skin if heated too fast or left unstirred. Stirring while it heats and watching for the first boil helps keep the soup smooth.

Swap the celery

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

  1. Garlicfits better
  2. Parsleyfits better
  3. Thymefits better
  4. Celerythe original

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