Instructions

  1. Place the potatoes and celery root in a large heavy saucepan.
  2. (I start the celery root first, since I find it takes longer to cook. It must be soft to mash up creamy).
  3. Cover with water and season liberally with salt and pepper.
  4. Cover and cook over medium-high heat until water boils.
  5. Reduce the heat to medium and continue to boil until the vegetables are tender, about 20 minutes.
  6. Drain, and mash the vegetables with a potato masher or a large fork.
  7. Mix in cream.
  8. Adjust seasoning with additional salt and pepper.
