Instructions

  1. Cover potatoes with salted cold water by 1 inch in a large saucepan and simmer, uncovered, until tender, 20 to 30 minutes.
  2. While potatoes are simmering, bring cream, butter, salt, and pepper to a simmer in a small saucepan. Remove from heat and keep warm, covered.
  3. Drain potatoes in a colander and cool slightly. Peel potatoes and mash in large saucepan.
  4. Stir spinach into warm cream, tossing to coat, and when slightly wilted (after about 1 minute), immediately add to potatoes. Mash potatoes until almost smooth. Serve immediately.
