Wash and dry produce.

Zest and quarter lime (for 4 servings, zest one lime and quarter both). Thinly slice jalapeño into rounds, removing ribs and seeds for less heat. Thinly slice radishes. Roughly chop cilantro.

In a small bowl, combine red pepper crema, mayonnaise, lime zest to taste, and chipotle powder to taste. Add water 1 tsp at a time until mixture reaches a drizzling consistency. Season with salt and pepper.

In a second small microwave-safe bowl, combine jalapeño, radishes, juice from half the lime, 1 tsp sugar (2 tsp for 4 servings), and a pinch of salt. Microwave for 30 seconds. Set aside, stirring occasionally, until ready to serve.

In a medium bowl, combine cabbage, half the cilantro, juice from remaining lime, 1 tsp sugar (2 tsp for 4), salt, pepper, and remaining lime zest to taste.

In a large bowl, whisk together tempura batter mix, half the Blackening Spice, ⅓ cup cold water, and ½ tsp salt (⅔ cup cold water and 1 tsp salt for 4 servings) until smooth. TIP: If mixture is too thick, add more water 1 TBSP at a time until it reaches a pancake-batter-like consistency.

Pat tilapia* dry with paper towels, then slice into strips (ours were about 1 inch wide). Season all over with remaining Blackening Spice, salt, and pepper.

Stir strips into batter until evenly coated.

Heat a ¼-inch layer of oil in a large, heavy-bottomed pan over medium-high heat.

Once oil is hot enough that a drop of batter sizzles when added to the pan, add coated fish in a single layer, working in batches. (Shake off excess batter before adding.) Cook until golden brown and cooked through, 1-2 minutes per side. TIP: To check for doneness, cut one strip in half.

Using tongs or a slotted spoon, transfer to a paper-towel-lined plate. Immediately season with salt and pepper.

Meanwhile, wrap tortillas in damp paper towels. Microwave until warm and pliable, 30 seconds.

Divide tortillas between plates; fill with slaw (draining first) and fried tilapia.

Top with chipotle mayo, remaining cilantro, and pickled jalapeño and radishes (draining first) to taste. Serve.
