Creating Mexican Street Corn and Shrimp is straightforward when you follow these steps:

1. Prep the Shrimp: In a mixing bowl, combine the shrimp with olive oil, chili powder, cumin, garlic powder, salt, and pepper. Toss until the shrimp are well-coated.

4. Make the Sauce: In a small bowl, combine the mayonnaise, lime juice, and salt. Mix well until smooth.
5. Combine Ingredients: In a large serving bowl, combine the charred corn, cooked shrimp, and mayo mixture. Toss until evenly distributed.
6. Add Cheese and Cilantro: Top with crumbled cotija cheese and chopped cilantro, then gently mix to incorporate.
7. Serve: Transfer to a serving dish and serve immediately, garnished with lime wedges.
