For the tartar sauce, combine mayonnaise, lemon juice, dill, pickles, and capers in a small bowl. Season with salt and pepper to taste.
For the fish, preheat oil to 350 degrees in a heavy bottom pan or deep fryer. In a medium bowl, whisk together corn starch, 1 cup flour, paprika, baking powder, cayenne, salt, and black pepper. Add beer to dry ingredients and mix; the batter should be similar to that of pancake batter. Add remaining 1/2 cup flour to a plate.
Season fish generously with salt and pepper. Work with one filet at a time, fully coat fish in flour, then dip both sides of fish into batter, making sure to let excess barrer drip back into the bowl. Then, coat fish in flour again; this creates the crunchy bits of batter. Repeat this process with the remaining fish.
Carefully add fish to oil and fry until crispy to touch and golden, abut 8-10 minutes. You will most likely need to turn the fish occasionally to ensure even crisp. Remove to a towel lined plate and immediatly season.
For presentation, spread a layer of tartar sauce on each half of the buns. Top with fish, red onions, lettuce, tartar sauce and Dilly Garlic Pickle Chips.
Enjoy!
