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

What each ingredient does

Large mealy potatoes
Starch that breaks down during simmering to give the soup its body and thickness.
Butter
Adds fat and richness, giving the soup a smoother mouthfeel and rounder flavor.
Milk
Adds creaminess and dairy richness, softening the flavor of the potato base.

The step that matters

Pureeing through a fine sieve or tammy. Cooked potato cells break down into a smooth, starchy mass that can turn gluey if overworked. Pressing gently through a fine sieve keeps the texture silky rather than pasty.

Swap the parsley

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

  1. Cinnamonfits better
  2. Marjoramfits about as well
  3. Nutmegfits about as well
  4. Parsleythe original

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