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 cooks down into a soft, fluffy mash.
Butter
Adds fat for richness and a smooth, silky mouthfeel.
Milk
Adds moisture and loosens the mash to a creamy consistency.
Egg yolk
Adds richness and helps the surface brown when brushed on and heated.

The step that matters

Drain and dry the potatoes completely. Excess water left on boiled potatoes dilutes the mash and makes it gluey or loose. Drying lets the starch stay fluffy and lets the butter and milk blend in properly.

Swap the potato

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

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

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