Rinse the halibut and cut into sticks. Approximately 1/2" wide and 3 " long.
Whisk together arrowroot, water, sea salt, black pepper and dried thyme. Place coconut in a separate bowl.
Begin heating a 12" skillet over medium heat. Dip the fish in arrowroot mixture and then into the coconut. Press the coconut into the fish to coat evenly.
Add 2 Tb. of oil to pan. Cook fish 4-6 minutes. Avoid overcrowding the pan so this may require cooking in batches. Serve.
