Place the potato and celeriac in a saucepan and cover with cold water. Bring to the boil over medium heat and cook for 25 minutes or until tender.
Meanwhile, in a small frypan, cook the speck with a knob of butter until crispy.
Drain potatoes. Return to the pan. Cook over low heat for 2-3 minutes or until dry. Use a potato masher to mash until smooth. Gradually mash in the butter and milk. Season with salt and white pepper.
Top with speck batons, drizzle with pan juices and sprinkle with baby herbs.
