1. Place potatoes in a large pot, cover with cold water, add a pinch of salt, and bring to a boil. 2. Reduce heat and simmer until potatoes are fork-tender, about 15–20 minutes. 3. Drain well and return potatoes to the hot pot to dry briefly over low heat. 4. Heat milk (and butter, if desired) until warm, then mash potatoes using a masher or ricer while gradually adding the warm milk and butter. 5. Stir in sour cream or cream cheese if using, season with salt and pepper, and adjust consistency with extra milk if needed. 6. Serve hot with a pat of butter and a sprinkle of pepper.
