Peel the potatoes and cut them into evenly sized chunks for even cooking.

Place the potato chunks in a large pot and cover with cold water. Add a pinch of salt.

Bring the water to a boil over high heat, then reduce to a simmer. Cook for 15-20 minutes or until the potatoes are fork-tender.

Drain the potatoes well and return them to the pot. Let them sit for a minute to allow excess moisture to evaporate.

Add the butter, milk, salt, and black pepper to the pot. Mash the potatoes with a potato masher or use a hand mixer for a smoother texture.

Taste and adjust seasoning if needed. Serve hot with extra butter on top if desired.
