Peel the potatoes and set aside. Rinse any excess dirt off under cold water. Dice the potatoes into approximately 1-inch cubes. Add the diced potatoes to an enameled Dutch oven and cover with water. Bring the water to a boil over medium-high heat for 30 minutes until fork tender and drain.
Once mashed, add the heavy cream, milk, and cheeses. Whip again with the handheld mixer until all is combined and smooth. Add more milk as needed until the desired consistency is met.
Any cheese you like! Don’t skip out on the cream cheese, but otherwise you can make any variation of this your heart desires. Pick one to be the star of the show that has more flavor than the others. The next two should be subtle and complimentary to the first. Ask at your local grocer what ones they would pair together and let your imagination go!
