I think he soaks it in cold water for a day or so, then rolls it in flour or corn meal, fry's it a bit, and then bakes it for a couple of hours. I might be wrong though.
Having seen what these things will eat is likely why I am reluctant to eat one. Rotten meat, and anything it encounters like snakes and dead fish. I once had a cow die and fall in the seasonal creek that runs out of my reservoir. When we went to pull it out of the creek there were three large snappers that came with it as we drug it up on the pasture.
