01 - Cook 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 kernels, heat a skillet over medium-high heat and char the corn until lightly browned, about 5 minutes. Remove from heat and let cool completely.
03 - In a large mixing bowl, add the cooled pasta, charred corn kernels, diced red onion, red bell pepper, jalapeño, and chopped cilantro. Toss gently to combine.
04 - In a separate bowl, whisk together mayonnaise, sour cream, lime juice, lime zest, chili powder, smoked paprika, cumin, hot sauce, salt, and black pepper until smooth and well blended.
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 cotija or feta cheese, reserving the remainder for garnish. Transfer to a serving bowl and sprinkle with the reserved cheese.
07 - Refrigerate the salad for at least 20 minutes to allow flavors to meld. Serve chilled for optimal taste and texture.
