For years I have used Town House butter flavored crackers crushed up with Italion bread crumbs, add some flour and a variety of seasoning like onion powder, garlic powder, Mrs Dash, etc all to taste. Dry fillets in flour dusting, roll in eggwash then roll on coating mixture. I use canola oil at 375 degrees and drop my perch fillets into the oil for 2 min for small pieces up to 2.5 minutes for bigger fillets. Leaves a thinner light great tasting coating that enhances the taste of the fish. Have had many people that dont care for fish like this recipe...also nake my own tarter sauce...2/3 helmans mayo, 1/3 miracle whip, add sweet pickle relish enough to make it noticible in the sauce, then add a small squirt of lemon juice, stirr well, keep refrigerated. Better than any store bought !!
