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 and, once mashed, give its soft, fluffy body.
Butter
Adds fat and richness, coating the starch for a smoother, silkier texture.
Milk
Adds moisture and softness, helping the mash turn creamy rather than dry.

The step that matters

Mash the potatoes until smooth. Mashing breaks down the starch cells while they are still hot. Overworking or letting them cool can make the mash gluey or lumpy, so add the warm butter and milk while the potatoes are hot.

Swap the potato

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

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

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