What each ingredient does

Potatoes
Provide the starchy base that becomes soft, fluffy and smooth when mashed.
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

Mash the potatoes until smooth. Overworking cooked potatoes releases excess starch, which makes the mash gluey and dense. Mash until smooth and stop once the texture is even.
