Ingredients
  

Fish
  • 1.5 lbs tilapia fillets or any firm white fish
  • 3 tbsp Kinder's Blackened Rub No Kinder's? Use instead: 1.5 tsp smoked paprika, 0.5 tsp cayenne, 0.5 tsp garlic powder, 0.25 tsp onion powder, 0.25 tsp dried oregano, 0.25 tsp dried thyme, 0.25 tsp black pepper, 0.5 tsp salt — combined to replicate the blend
  • 2 tbsp olive oil or avocado oil
Lime Crema
  • 1/2 cup sour cream
  • 2 tbsp lime juice
  • 1 tsp lime zest
For Serving
  • 12 small corn or flour tortillas
  • 2 cup shredded purple cabbage
  • 1 cup shredded green cabbage
  • 1 avocado, sliced
  • Fresh cilantro, chopped
  • Lime wedges
  • Sliced jalapenos optional

Equipment

  • Cast-iron skillet or heavy stainless steel pan
  • Fish spatula
  • Two mixing bowls
  • Griddle or gas burner
  • Microplane or zester

Method
 

  1. Pat the tilapia fillets completely dry with paper towels — dry fish = crispy crust.
  2. Press Kinder's Blackened Rub into both sides of each fillet, coating evenly.
  3. Heat oil in a cast-iron skillet over medium-high heat until very hot but not smoking. You want the pan shimmering.
  4. Carefully lay the fillets in the hot pan. Cook for 3-4 minutes without touching them — let that crust develop.
  5. Flip the fish with a fish spatula and cook another 3-4 minutes until cooked through and the fish flakes easily with a fork.
  6. Remove from heat and rest 2 minutes. Break or slice into large chunks.
  7. While the fish cooks, toss together both shredded cabbages in a bowl.
  8. In a small bowl, mix sour cream, lime juice, and lime zest for the crema.
  9. Warm tortillas on a griddle or briefly over a gas flame until pliable and slightly charred at the edges.
  10. Assemble the tacos: fish first, then cabbage, a drizzle of lime crema, avocado slices, cilantro, and jalapenos if you want the heat. Finish with a squeeze of fresh lime.

Notes

  • Get the pan ripping hot before the fish goes in — This is the whole game. A pan that's not hot enough means steam instead of sear, and you'll end up with gray fish instead of a blackened crust. Heat the oil until it shimmers and a drop of water evaporates immediately on contact.
  • Don't touch the fish after it hits the pan — Leave it completely undisturbed for 3–4 minutes. The crust releases naturally from the pan when it's ready. If it's sticking, it's not done yet — wait.
  • Swap the fish freely — Tilapia is affordable and forgiving, but mahi-mahi, cod, snapper, or any firm white fish works here. Avoid thin, delicate fillets that fall apart under high heat.
  • Nonstick won't cut it — Cast iron is ideal; it holds heat evenly and handles the high temp required for blackening. A heavy stainless steel pan is the next best option. Nonstick can't get hot enough for a real crust.
  • Add mango salsa for contrast — The sweetness cuts directly against the bold, spiced fish. It's not required, but it's a solid move.
Serving Suggestions
  • Set up a taco bar and let people build. Put out extra lime crema, sliced jalapeños, mango salsa, and fresh cilantro so everyone can dial in the heat and brightness.
  • Grilled corn on the cob brushed with chili-lime butter is the natural side — it keeps the summer cookout energy going without overcomplicating the spread.
  • For drinks, a cold Mexican lager or a margarita on the rocks cuts through the bold blackened spice cleanly. Sparkling water with lime works if you're keeping it simple.
Storage & Reheating
  • Store the cooked fish separately from the toppings and tortillas. In the fridge, it holds well for up to 2 days.
  • To reheat, skip the microwave — it turns the fish rubbery and kills the crust. Use a dry skillet over medium heat, about 2–3 minutes per side, to bring the texture back.
  • Assemble the tacos fresh when you're ready to eat. The slaw and crema hold separately in the fridge for the same 2 days.
