Here is a quick fish-coating mix to pack and take along on a picnic or fishing trip. For extra crunch, use cornmeal instead of flour.
At home, mix the dry ingredients in a large, sealable plastic bag. At the site, clean and filet the fish. Shake the cleaned fish in the bag of dry mix. Heat the butter or oil in a heavy frying pan set on a grill about 1 inch above hot coals. Cook the coated fish for 6 minutes, flip, and continue cooking until it flakes. Makes 4 servings.
