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

What each ingredient does

Potatoes
Provide the starch that forms the bulk and soft structure of the mash.
Butter
Adds fat for richness and a smooth, silky mouthfeel.
Milk
Adds moisture and creaminess, loosening the mash to a smooth consistency.

The step that matters

Beat the mixture briskly over the heat for 1-2 minutes. Potato starch granules are fragile once cooked. Beating them too long or too hard ruptures the granules and releases excess starch, which turns the mash gluey and gummy. Keep the beating brief and stop once the mash is smooth and hot.

Swap the potato

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

  1. Potatothe original
  2. Capsicumfits about as well
  3. Tomatofits less well
  4. Asparagusfits less well

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