Peel the potatoes to remove the skin.

Chop the potatoes into uniform 1-2 inch pieces.

Place the potatoes in a large pot, cover with cold water, add a generous pinch of salt, and bring to a boil over high heat.

Cook the potatoes for 15-20 minutes, or until fork-tender.

Drain the potatoes in a colander to remove excess moisture.

Return the drained potatoes to the pot, add the butter, and mash until smooth.

Gradually pour in the milk while continuing to mash, adjusting the consistency to your liking.

Season with salt and black pepper to taste and stir to combine.
