01 - Boil pasta according to package directions until al dente. Drain thoroughly and rinse under cold running water to stop cooking and cool completely.
02 - If using fresh corn, heat a skillet over medium-high heat and add corn kernels. Cook, stirring occasionally, until lightly charred and browned, about 5 minutes. Let cool completely.
03 - In a large mixing bowl, add cooled pasta, charred corn, diced red onion, red bell pepper, jalapeño, and chopped cilantro. Toss gently to distribute evenly.
04 - In a separate medium bowl, whisk together mayonnaise, sour cream, lime juice, lime zest, chili powder, smoked paprika, cumin, hot sauce, salt, and black pepper until completely smooth and creamy.
05 - Pour the prepared dressing over the pasta and vegetable mixture. Toss thoroughly until all ingredients are evenly coated with the creamy dressing.
06 - Gently fold in all but 2 tablespoons of the crumbled cotija or feta cheese, being careful not to break up the cheese too much.
07 - Transfer salad to a serving bowl or platter. Sprinkle reserved cheese over the top along with additional fresh cilantro if desired. Refrigerate for at least 20 minutes before serving to allow flavors to meld.
