Most fish fry coatings are formulated for frying, baking and broiling. For frying, common guidance is to preheat oil to about 350°F for pan-frying and about 375°F for deep-frying. Instructions may also include pan-frying and deep-frying options and a baking or broiling method on the package.
Package sizes commonly range from about 8 ounces up to 22 ounces, depending on brand and formulation.
One box typically coats about 5 pounds of fish, with many mixes stating coverage in the 5–7 pound range per box.
Moisten the fish before dredging—commonly by mixing about 1/2 cup milk with 1 egg—and dip the fish in that mixture before coating. Packages often note that using milk and egg yields a thicker, heartier crust.
Typical instructions recommend frying at about 350–375°F. Cook times vary by method and thickness—examples include pan-frying about 2–3 minutes and deep-frying about 3–5 minutes.
