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 form the body of the mash.
Cream or sweet milk
Adds moisture and richness, softening the texture and carrying fat.
Butter
Adds fat for richness and a smooth, silky mouthfeel.
Egg white
Adds protein that sets lightly on heating, helping the mash hold its fluffy structure.

The step that matters

Beat the heated mixture into the mashed potatoes until light and fluffy. Beating incorporates air into the warm starch and protein mixture, lightening the texture. Overbeating potatoes can release starch and turn them gluey, so stop once smooth and light.

Swap the white pepper

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

  1. Nutmegfits better
  2. Parsleyfits better
  3. Tarragonfits better
  4. White pepperthe original

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