Start by washing and peeling the potatoes. Once the potatoes are peeled, place them in a colander and rinse them again with cold water. Next, chop the potatoes into large chunks.
Place the potatoes in a large pot and cover with cold water. Stir in 1 ½ teaspoon of salt. Heat the pot over medium-high heat and bring it up to a boil. Boil the potatoes for 12-14 minutes or until they can easily be pierced with a fork. Drain the potatoes in a colander and place them in a large bowl.
Next, add the milk and butter to a small pot or in the same pot that the potatoes were cooked in. Heat the pot over medium-low heat for a couple minutes. As soon as the butter melts and the milk is warm, remove the pot from the heat. Do not boil the milk.
Now pour the warm milk and butter over the potatoes half at a time. Using a hand mixer blend the potatoes on low speed until you reach a smooth consistency. Be careful not to overmix at this point. Taste the potatoes and add any additional salt or pepper. I added ¼ teaspoon of salt and ⅛ teaspoon of freshly cracked black pepper. Enjoy!
