Spicy Blackened Fish Tacos

Set a large well-seasoned cast-iron skillet over medium-high heat

If your skillet is not well-seasoned, add 1 to 2 teaspoons neutral oil before cooking the corn

Add 2 cups corn kernels to the skillet and sear, undisturbed, until nicely browned

Stir, then repeat 1 to 2 more times until the corn kernels are well-toasted with charred spots

Remove the skillet from the heat and transfer the corn to a medium bowl with 1 small clove finely grated garlic

Let cool until warm

Stir in 1 tablespoon lime juice, ¼ cup fresh cilantro, 2 tablespoons freshly grated Cotija cheese (if using), ¼ cup mayonnaise, ½ teaspoon mild chili powder, and salt to taste

Add 2 cups finely shredded cabbage to a medium bowl and massage with a good pinch of salt to help soften the leaves

Add 2 cups cubed ripe mangoes, 1 finely minced shallot, ¼ cup minced cilantro, the juice from 1 mandarin orange, and 2 teaspoons lime juice to the cabbage bowl

Season the mango slaw to taste

Cut 12 ounces firm white fish into 4 portions and pat dry

In a small bowl, combine 2 teaspoons smoked paprika, 1 teaspoon mild chili powder, 1 teaspoon ground cumin, and ¾ teaspoon Diamond-Crystal Kosher Salt (or ½ teaspoon Morton Kosher Salt)

Coat the fish portions with 2 teaspoons neutral oil, then rub the spice mixture evenly on all sides

Gently tap off any excess seasoning before cooking

Set a large seasoned cast-iron skillet or non-stick skillet over medium-high heat with 2 tablespoons neutral oil

Once the oil is hot, add the fish portions and sear until the bottom is nicely browned

Flip the fish and cook until cooked through and flaking easily with a fork, about 2 minutes more for thinner fillets and 3 to 4 minutes more for thicker portions

Transfer to a plate and keep warm

Warm 4 corn tortillas on a skillet or directly over a gas flame

Place a piece of blackened fish in the center of each warm tortilla, then top with a spoonful of the mango slaw and the elote salad

Serve warm with lime wedges and thinly sliced radishes (if desired)
