You clean them the same way I do... I take cornmeal, some pepper, salt, paprika (Hungarian red is the best), and some garlic powder. Mix all that together, and then after you have the filet's clean and cold, dip them in beaten egg, roll them in the cornmeal seasoning and lay them in hot olive or canola oil in a cast iron fry pan. When they start to turn white, flip and do the other side.. Those slimy ugly devils are suddenly very good looking on a plate with serving of some whole kernel corn and cole slaw...

I have a friend that fishes Superior all the time on the ice, and he will not mess with them, so he brings me a bunch of them. I just clean them all up and freeze them in milk cartons with water. Then when I want fish, I unthaw the milk carton of them and make up a mess ....
