Creating Baja Fish Tacos is a rewarding experience. Follow these steps to achieve the best results:

1. Prepare the Fish: Rinse the fish fillets under cold water and pat them dry. Cut the fish into strips for easy handling.
2. Season the Flour: In a shallow dish, combine the flour, cornmeal, paprika, cumin, chili powder, salt, and pepper.
3. Mix Buttermilk: Pour the buttermilk into another shallow dish.
4. Coat the Fish: Dip each fish strip first into the buttermilk, allowing excess to drip off. Then coat with the flour mixture, pressing gently to ensure a nice coverage.
5. Heat the Oil: In a large frying pan, heat about an inch of oil over medium-high heat until shimmering.
6. Fry the Fish: Carefully place the coated fish strips into the hot oil, frying in batches to avoid overcrowding. Fry until golden brown, about 3-4 minutes per side. Remove and place them on paper towels to drain excess oil.
7. Warm the Tortillas: In another skillet, warm the tortillas over medium heat until soft, about 30 seconds per side. Keep them warm in a towel.
8. Prepare the Sauce: In a small bowl, whisk together the sour cream, mayonnaise, lime juice, and a pinch of salt to create a creamy sauce.
9. Assemble the Tacos: Place a few pieces of fried fish on each tortilla. Top with shredded cabbage, cilantro, and avocado slices. Drizzle with the creamy sauce.
10. Serve with Lime: Serve immediately with lime wedges on the side for a fresh burst of flavor.
