What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Pat the basa fillets extremely dry before seasoning to ensure a dark, crusty sear rather than steaming the fish.
- 2Heat the cast iron skillet until the oil is shimmering and just beginning to smoke before adding the fish for proper blackening.
- 3Cook the fish in batches if needed; overcrowding drops the pan temperature and creates steam, ruining the crust.
- 4For the slaw, let it sit for 5-10 minutes after tossing with lime juice so the cabbage softens slightly and absorbs the tangy flavor.
- 5Warm tortillas in a dry skillet until lightly charred in spots; this adds smoky flavor and makes them pliable without drying out.
- 6Assemble tacos just before serving to keep the tortillas from becoming soggy from the slaw and sour cream.

Mango Avocado SlawMango-Avocado Slaw
Replace half the cabbage with diced mango and avocado, and use a lime-honey dressing for a sweeter, creamier contrast to the spicy blackened fish.
