In a medium mixing bowl, combine the peeled shrimp with chili powder, ground cumin, minced garlic, fresh lime juice, and a pinch of salt and pepper. Toss the shrimp thoroughly until they are evenly coated with the spice mixture. Allow the shrimp to marinate for 15 minutes to enhance flavor.
In a separate bowl, mix the diced mango, finely chopped red onion, and minced jalapeño. Season the mixture with a pinch of salt and a drizzle of lime juice. Stir gently to combine and set aside.
Heat a large skillet over medium-high heat and add the olive oil. Once the oil shimmers, add the marinated shrimp in a single layer. Cook the shrimp for approximately 2-3 minutes on each side, or until they turn pink and opaque. Remove from heat and set aside.
To prepare the tortillas, warm them in a dry skillet for about 30 seconds on each side until soft, or wrap them in aluminum foil and heat them in a 350°F oven for about 10 minutes.
To assemble each taco, place a few cooked shrimp on one half of each tortilla. Top the shrimp with a generous scoop of the prepared mango salsa, and garnish with freshly chopped cilantro.
Present the tacos on a platter, accompanied by lime wedges for an extra kick of brightness. Encourage diners to squeeze lime over their tacos right before enjoying for added zest.
Notes
Adjust the jalapeño according to your heat preference.
