The secret is warm dairy and a gentle hand with the masher. Overwork them and they turn gluey; treat them right and they are the best thing on the plate.

Steps
Cover the potatoes with cold salted water by an inch. Bring to a boil and cook 18 minutes, until a knife slides in easily. Drain well and return to the hot pot for 1 minute to steam dry.
Warm the butter and milk together in a small pan until the butter melts.
Mash the potatoes, then beat in the warm butter mixture, sour cream, and pepper. Season with salt to taste. Serve hot.
Tip: Warm the milk before it goes in. Cold dairy cools the potatoes and they never quite come together.
