01 - Pat cod fillets dry and cut into 8 uniform strips, approximately 4 inches each.
02 - Arrange three shallow bowls: place flour in the first, beat eggs in the second, and combine panko breadcrumbs with paprika, garlic powder, salt, and black pepper in the third.
03 - Dredge each cod strip in flour, then coat in beaten egg, and finish by thoroughly covering with the seasoned panko mixture.
04 - Heat 1/2 inch of vegetable oil in a large skillet over medium-high heat. Fry cod in batches for 2 to 3 minutes per side until golden and cooked through. Remove and drain on paper towels.
05 - In a small bowl, mix sour cream, mayonnaise, lime zest, lime juice, minced garlic, chopped cilantro, and a pinch of salt. Chill until required.
06 - Heat tortillas in a dry skillet or in the microwave just before assembling.
07 - Layer shredded cabbage, julienned carrot, and sliced red onion on each warmed tortilla. Top with a crispy cod strip, drizzle with lime-cilantro sauce, and garnish with cilantro leaves. Serve immediately with lime wedges.
