Recipe for the most fluffy mashed potatoes.
PREP THE POTATOES: Start with a large bowl of water near your work station. As you peel and cut up the potatoes, submerge the potatoes under the water in the bowl to keep them from turning pink while they are uncooked.
ADD THE OTHER INGREDIENTS: Add a pinch of baking soda (this is key for the ultimate fluffiness). Add the cream cheese, butter, cream, and salt.
MASH THE POTATOES: Use a potato masher to mash the potatoes and to mix them together with the other ingredients. Continue mashing until they are light and fluffy. Add more salt and pepper to taste as desired.
FOR SERVING: Move the mashed potatoes to your serving dish and add more sliced butter on top for serving.
