This is my kids' favorite way to have potatoes. In fact, there was a mutiny one year when I thought I would try a new recipe with the Christmas ham! Needless to say, no matter what I make for Christmas dinner, I always have to have ham and these mashed potatoes! These are my father-in-law's favorite too!
Place peeled, cubed potatoes in a large pot and cover in water an inch higher than the potatoes. Add a bit of salt. Bring to a boil over high heat. Lower heat to medium and boil for 20 to 25 minutes or until potatoes are fork tender.
Heat half-and-half, butter and salt (2 to 3 teaspoons) in saucepan over medium-low heat until smooth, about 5 minutes. Keep warm.
Drain potatoes and transfer to large bowl (or keep in the large pot). With electric mixer on medium-low speed, beat potatoes til no longer chunky, slowly adding half-and-half mixture, until smooth and creamy, about 1 minute. Scrape down bowl.
Taste potatoes and add more milk, butter or salt as needed.
