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 - Heat skillet over medium-high heat. Add fresh corn kernels and cook, stirring occasionally, until lightly browned and charred in spots, about 5 minutes. Let cool completely.
03 - In large mixing bowl, combine cooled pasta, charred corn, red onion, bell pepper, jalapeño, and cilantro. Toss gently to distribute evenly.
04 - In separate bowl, whisk together mayonnaise, sour cream, lime juice, lime zest, chili powder, smoked paprika, cumin, hot sauce, salt, and pepper until smooth and well combined.
05 - Pour dressing over salad mixture. Toss thoroughly until all ingredients are evenly coated with creamy dressing.
06 - Gently fold in all but 2 tablespoons of crumbled cotija or feta cheese, being careful not to break down pasta pieces.
07 - Transfer to serving platter or bowl. Sprinkle reserved cheese over top along with additional cilantro if desired. Refrigerate at least 20 minutes before serving to allow flavors to meld.
