Place potatoes in a large stock pot. Add 1/2 teaspoon salt. Add water until potatoes are covered. Bring to a boil, reduce heat and simmer, covered, 15-20 minutes or until done.

Warm whipping cream and butter, together in a microwave safe dish. Drain water from potatoes. Put hot potatoes into a large bowl. Add whipping cream and butter to potatoes. Mash potatoes well, using a potato masher. Use a strong spoon to beat further, adding milk to achieve desired consistency. (Do not over-beat or your potatoes will get gluey). Add salt and pepper to taste. Serve immediately.
