Instructions

1. Step 1: In a large bowl, whisk together 1 cup all-purpose flour, 1 tsp baking powder, 1 tsp salt, and 1/2 tsp black pepper. Gradually add 1 cup cold lager beer, whisking until the batter is smooth and slightly thick.
2. Step 2: Heat 4 cups vegetable oil in a deep skillet or fryer to 350°F.
3. Step 3: Pat dry 4 cod fillets (6 oz each). Dip each fillet into the beer batter, allowing excess to drip off, then carefully lower into hot oil. Fry each piece for 4-5 minutes until golden brown and cooked through. Remove and drain on paper towels.
4. Step 4: Meanwhile, in a small bowl, combine 1/4 cup ketchup, 1/2 cup mayonnaise, 2 tbsp dill pickle relish, 1 tbsp lemon juice, and 1/2 tsp dried dill. Mix well to create tangy tartar sauce.
5. Step 5: Toast 4 hamburger buns on a grill or skillet until lightly golden.
6. Step 6: Assemble sandwiches by spreading 2 tbsp tartar sauce on each bun bottom, topping with 1 fried fish fillet, 1 large lettuce leaf, and 2 slices of tomato. Cover with the bun top and serve immediately.
