How to Make It
Step 1
Cover potatoes with cold, salted water in a large pot and bring to a boil; boil for 5 minutes. Add parsnips and boil until vegetables are cooked through, 15 to 20 minutes. Drain and return to pot.
Step 2
Shake pot over low heat to dry vegetables slightly. Add butter, cream, salt, pepper and, if desired, nutmeg. Mash with a potato masher to desired consistency. Sprinkle with parsley, if desired, and serve hot.
