What each ingredient does

Potatoes
Their starch gives the mash its body and structure once cooked and broken down.
Hot milk or cream
Adds moisture and softens the mash, giving it a smooth, creamy texture.
Butter
Adds fat, which carries flavor and makes the mash taste richer and smoother.

The step that matters

Stirring in the milk mixture. Overworking mashed potatoes ruptures starch cells and releases excess starch, which makes the texture gluey. Stir gently only until the liquid is absorbed and the mash looks light.
