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

What each ingredient does

Potatoes
Form the bulk of the dish; their starch becomes soft and fluffy when mashed.
Butter
Adds fat and richness, giving the mash a smoother mouthfeel and flavor.
Milk
Adds moisture and softness, helping the mash turn creamy when mixed in.

The step that matters

Boil until tender. Potatoes that are undercooked stay firm and grainy when mashed, while thorough cooking lets the starch soften so the mash turns smooth.

Swap the celery

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

  1. Parsleyfits better
  2. Thymefits better
  3. Cinnamonfits better
  4. Celerythe original

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