01 - Prepare pasta according to package directions until al dente. Drain thoroughly and rinse under cold 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 browned and charred in spots, approximately 5 minutes. Let cool completely.
03 - In a large mixing bowl, add the cooled pasta, charred corn, diced red onion, red bell pepper, jalapeño, and chopped cilantro. Toss gently to distribute evenly.
04 - In a separate bowl, whisk together mayonnaise, sour cream, fresh lime juice, lime zest, chili powder, smoked paprika, ground cumin, and hot sauce until smooth and well combined. Season with salt and black pepper to taste.
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 approximately 2 tablespoons of the crumbled cotija or feta cheese, reserving the remainder for garnish.
07 - Transfer the salad to a serving platter or bowl. Sprinkle the reserved cheese over the top along with additional fresh cilantro if desired.
08 - Refrigerate the pasta salad for at least 20 minutes to allow flavors to meld. Serve chilled for optimal taste and texture.
