Knead into a ball, transfer to a sheet of parchment paper, and loosely form a rectangle.
Sandwich with another piece of parchment paper, and roll out with a pin to about 1/4" thick.
Cut to desired width, fry in oil at medium heat until golden brown (or a bit darker), dry on a paper towel, and season with whatever tickles your fancy!
Notes
Make sure to sprinkle the xanthan gum across all the flour, and whisk together. It will immediately gel up with the water, so the more evenly spread out it begins, the better.
