The traditional Minnesota recipe is to fillet them, batter the fillets, and deep fry them. Then wrap bacon around the fried fillet, batter it again, then fry that. Then attach cheese curds to the fillet, batter it again, and fry it again. Then batter it once more and fry it again. Make sure you use a little baking powder in the batter so it soaks up more grease. Be sure the grease is rancid before cooking. Serve with bacon, cheese curds, and rancid grease. Put the fillets on a plate and cover them with undiluted canned mushroom soup.
However, I like to lightly flour the fillets, and pan fry them until just done. Serve with tartar sauce.
