What each ingredient does

Potatoes
Form the main body of the dish, becoming soft and fluffy when boiled and mashed.
Butter
Adds richness and a smooth, silky mouthfeel to the mashed potatoes.
Milk
Adds moisture and loosens the mash, giving it a creamier texture.

The step that matters

Beat the mixture well. Beating after adding butter and milk works the starch released from the potatoes, so the mash turns smooth and creamy. Overworking it, especially with a blender or food processor, can make it gluey.
