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 mash its bulk and body.
Hot milk
Adds moisture and softness, loosening the starch for a smooth texture.
Butter
Adds fat for richer flavour and a silkier mouthfeel.

The step that matters

Beat the mixture until very light and fluffy. Beating works the potato starch and incorporates air, which gives a light texture. Overworking a starchy potato, however, can make it gluey, so beat only until fluffy and stop.

Swap the parsley

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

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

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