Plenty of breading in supermarkets, and tried a few different one's, but sometimes it's better to do it yourself. I've tried to deep fry frog legs, perch, and crappie, only to have the breading fall off. Not sure if this
is new to anybody else, but Toasted Bread Crumbs work's great. Toast grounded up in a processor, and applied after the flour and an egg/milk wash sticks great. The flavor is good and I have used this on shrimp, crappie, perch, scallops, and mushrooms so far in deep frying!
