Back fish is usually breaded, so the fish remains juicy. It is best to use fillets for back fish fish so that you don't accidentally swallow a bone hidden under the breading. You can bake fish in the deep fryer or bake it in the oven. This makes the breadcrumbs nice and crispy. In addition to fish dishes, which are prepared with leaves of dough, there are also fish casseroles, which are baked in the oven.
