What each ingredient does

Potatoes
Starch that breaks down into a soft, fluffy body when mashed.
Butter
Adds fat for richness and a smoother mouthfeel.
Milk
Adds moisture that loosens the mash and makes it creamy.

The step that matters

Drying the potatoes after draining. Returning the drained potatoes to the heat evaporates surface water. Wet potatoes turn gluey and dilute the butter and milk, so a short dry gives a fluffier mash.
