Thoroughly scrub the potatoes under cool water. Peel if desired or leave the skins on for texture and appearance.
02 -
Cut potatoes into 1-inch pieces and transfer to a large pot. Cover with cold water and add 1/2 teaspoon salt.
03 -
Bring to a boil over high heat. Cook for 12–15 minutes, or until the potatoes are very tender when pierced with a fork but not falling apart. Drain thoroughly in a colander.
04 -
Return drained potatoes to the emptied hot pot. Allow to rest uncovered for 2–3 minutes to release excess moisture.
05 -
Add butter pieces to potatoes while hot. Use a potato masher to mash until smooth with some texture remaining.

Sprinkle in remaining 1/2 teaspoon salt, pepper, and half of the warmed milk. Stir to incorporate. Add the rest of the milk, and more if needed, to reach your preferred creaminess. Adjust seasoning to taste. Serve hot.
