What each ingredient does

Potatoes
Form the bulk of the dish, providing starch that gives mashed potatoes their body.
Butter
Adds fat for richness and a smooth, silky mouthfeel.
Milk
Adds moisture so the mash becomes smooth and spreadable.

The step that matters

Beat until well mixed and light. Overworking mashed potatoes, especially with a mixer, releases too much starch and makes them gluey, so beat only until the liquid and fat are evenly incorporated and the texture is light.
