Begin by peeling and chopping the russet potatoes into uniform one-inch pieces.

Place the chopped potatoes into a large pot filled with cold, salted water. Bring to a boil over medium-high heat, then simmer until fork-tender, about 15-20 minutes.

Carefully drain the potatoes and return them to the hot pot. Allow them to steam for a few minutes.

Add warm milk and unsalted butter to the pot. Use a potato masher to mash the potatoes until smooth and creamy.

Taste your creation! Adjust seasoning with salt and freshly cracked pepper.

Transfer the mashed potatoes to a serving dish, optionally topping with a small pat of butter.
