In a medium mixing bowl combine flour, baking powder, and pepper. Slowly whisk in 12 ounces of cold beer until a batter develops and most of the lumps are gone. In a separate dredging plate, combine 1/2 cup flour and 1 teaspoon salt.
Remove fish from refrigerator and pat dry with paper towel. Work with one piece of fish at a time and keep cooked fish warm in the oven. Dredge in flour and shake well to remove excess. Use tongs to transfer fish to batter and dredge to coat well. Allow excess to drip in to bowl before slowly lowering one inch of the fish in to the frying oil. Allow to fry for 5 seconds then carefully lower the fish away from you. Fry for 2 1/2 minutes per side for a medium thickness piece of fish.

Notes
Cooking time greatly depends on how much your making and how large your frying vessel is. I highly recommend using a frying thermometer to maintain consistent frying temperatures. This cuts down on time and ensures a light and crispy product.Instead of Malt Vinegar, use the vinegar from the Pickle Onions.
