  • 2 celeriacs (celery root), 1 1/2 lb. each, trimmed, peeled, cut into 1-inch chunks
  • Juice of 1 lemon
  • 8 to 10 medium Yukon Gold potatoes (about 3 1/2 lb. total), peeled, cut into 1-inch chunks
  • Salt and pepper
  • 1 cup whole milk
  • 4 tablespoons unsalted butter, cut into small pieces


  1. 1. Place celeriacs in a bowl. Cover with cold water; stir in lemon juice. Let stand while preparing remaining ingredients. Drain when ready to boil.
  2. 2. Place potatoes and celeriacs in separate pots; cover with cold water. Add a large pinch of salt to each pot; bring to a boil over high heat. Reduce heat to medium-low; cook until vegetables are very tender, about 30 minutes for potatoes and 15 to 20 minutes for celeriacs.
  3. 3. Drain celeriacs. Pulse in a food processor until smooth. Drain potatoes, return to pot and add celeriacs, milk and butter. Mash with a potato masher or put through a ricer. Season with salt and pepper. Serve.
