What each ingredient does

Potatoes
Starch provides the bulk and fluffy, absorbent body of the mash.
Butter
Fat adds richness and a smooth mouthfeel to the mashed potatoes.
Hot milk
Liquid loosens the mash and, with the butter, makes it creamy.

The step that matters

Drain and dry the potatoes thoroughly. Surface water left on the boiled potatoes dilutes the mash and makes it gluey or soggy. Drying lets the starch stay fluffy when mashed and absorb the milk and butter evenly.
