Fire up your grill with the Vortex BBQ. Let the coals get good and hot.
Combine all of the dry mixture ingredients in a pie plate.
In another pie plate, whisk together the eggs and water.
Working in batches, dip the chicken into the wet mixture, then into the dry mixture.
One more time, dip the chicken into the wet mixture and then the dry mixture.
Transfer chicken to your grill grate around the Vortex and cook until done, about 45 minutes.
Lightly brush the chicken with oil the last 5 minutes of cooking to get a crispier skin.
