Cut off the skin of the celery root and slice it first into even slices, about ¼-inch thick. Cut the slices into ¼-inch strips and place them in a medium mixing bowl.

When all of the roots are sliced and in the bowl, add the duck fat and toss to coat. Grate the fresh nutmeg over the fries, sprinkle some salt on, and again toss to mix everything together.

Spread the fries on the baking sheet in an even layer and place them in the oven. Bake for 20 minutes, then flip the fries using a spatula and return them to the oven for another 15 minutes.

Remove them from the oven and eat warm. Enjoy!
