Don't be intimidated by this gnarly looking vegetable, just treat it like a potato.

Trim one end off of the root. Place it, cut side down, on the cutting board.

Following the natural curve, trim all of the tough, outer skin away.

Continue around the entire celery root.

Finally, trim the other end away, and any other brown bits left, until the whole root is clean.

Now that the celery root is completely trimmed it needs to be immersed in acidulated water or it will oxidize.

Stand the root on its flat end to sturdy it. Cut thick slices of the celery root.

Cut these slices into equal planks.

Cut these planks into cubes.
