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

What each ingredient does

Potatoes
Provide the starch and bulk that give the soup its body when mashed.
Milk
Adds liquid and creaminess, thinning the mashed potatoes into a smooth soup.
Butter
Adds fat for richness and a smoother, rounder mouthfeel.
Onion
Infuses the milk with savory aroma as it heats.
Celery
Infuses the milk with a mild, herbal aroma as it heats.

The step that matters

Rub the mixture through a strainer. Mashed potatoes left lumpy or overworked can turn gluey or grainy. Pressing the mixture through a strainer breaks up remaining lumps for a smooth texture, so the soup should be strained while still hot.

Swap the celery

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

  1. Garlicfits about as well
  2. Parsleyfits about as well
  3. Thymefits about as well
  4. Celerythe original

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