Season and shape

  1. Mix in salt, butter, and milk or cream until well combined.

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

What each ingredient does

Potatoes
Starch gives the mash its body and structure once cooked and mashed.
Butter
Adds fat for richness, flavor, and a smooth, silky mouthfeel.
Milk or cream
Adds moisture and creaminess, loosening the mash for a soft texture.

The step that matters

Mashing the potatoes. Working cooked potatoes too vigorously ruptures starch cells and releases starch, which makes the mash gluey and gummy. Mash until smooth, then stop, and mix in the dairy gently.
