01 - Cook pasta according to package directions until al dente. Drain and rinse under cold water to stop cooking and cool completely.
02 - If using fresh corn, heat a skillet over medium-high heat and char kernels until lightly browned, about 5 minutes. Allow to cool completely.
03 - In a large bowl, combine cooled pasta, corn, red onion, red bell pepper, jalapeño, and chopped cilantro.
04 - Whisk together mayonnaise, sour cream, lime juice, lime zest, chili powder, smoked paprika, cumin, hot sauce (if using), salt, and black pepper until smooth and well combined.
05 - Pour dressing over pasta and vegetables. Toss thoroughly until all ingredients are evenly coated with the creamy mixture.
06 - Gently fold in most of the crumbled cotija or feta cheese, reserving a small portion for garnish.
07 - Transfer salad to a serving platter or bowl. Sprinkle remaining cheese on top along with extra cilantro if desired. Refrigerate for at least 20 minutes before serving to allow flavors to meld.
