What each ingredient does

Brook trout
Forms the main body of the dish, cooking to a flaky, tender texture when fried.
All-purpose flour
Forms a light coating that browns in the hot fat and helps crisp the surface.
Lard or fat from fried salt pork
Conducts heat for frying and carries flavor while crisping the flour coating.
Butter
Adds flavor to the frying fat and helps prevent the fish from sticking to the pan.

The step that matters

Frying the fish quickly over steady heat. Flour-coated fish browns through contact with hot fat. If the pan is too cool, the fish absorbs fat and turns greasy and soft, and if too hot, the coating burns before the fish cooks through. Browning one side fully before turning helps the coating set so it does not tear.
