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

What each ingredient does

Potatoes
Provide the starchy base that gives the soup its body and thickness.
Cream
Adds fat and richness, giving a smoother, silkier mouthfeel.
Milk
Adds liquid and mild sweetness, diluting the potato into a pourable soup.
Butter
Adds fat for richer flavour and a smoother, rounder texture.
Flour
Thickens the soup by swelling with liquid when heated, if used.

The step that matters

Strain the mixture through a sieve. Straining removes remaining potato fibres and lumps, so the soup turns smooth; skipping it leaves a grainy texture.

Swap the parsley

The recipe marks parsley as optional. How well each one fits the dish's main ingredients (potato, cream, milk, butter, flour, celery, pepper):

  1. Nutmegfits about as well
  2. Parsleythe original
  3. Thymefits less well
  4. Tarragonfits less well

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