Make the mash

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 becomes fluffy when mashed.
Butter
Adds richness and smooth mouthfeel to the mashed potatoes.
Hot milk
Adds moisture and creaminess, loosening the mash to a smooth texture.

The step that matters

Mash the potatoes until fine. Overworking cooked potatoes releases starch and can make them gluey, while under-mashing leaves lumps. Mash gently and add the warm liquid while the potatoes are still hot so they absorb it evenly.

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.
