01 - Prepare pasta according to package directions until al dente. Drain thoroughly and rinse under cold water to stop cooking process. Set aside to cool completely.
02 - If using fresh corn, heat skillet over medium-high heat and cook corn kernels until lightly charred and browned, approximately 5 minutes. Remove from heat and allow to cool.
03 - In a large mixing bowl, add cooled pasta, charred corn, diced red onion, bell pepper, jalapeño, and chopped cilantro. Toss gently to distribute evenly.
04 - Whisk together mayonnaise, sour cream, fresh lime juice, lime zest, chili powder, smoked paprika, ground cumin, and hot sauce until completely smooth and well combined. Season with salt and black pepper.
05 - Pour prepared dressing over pasta and vegetable mixture. Toss thoroughly until all ingredients are evenly coated with the creamy dressing.
06 - Gently fold in most of the crumbled cotija or feta cheese, reserving a small portion for garnish. Avoid over-mixing to prevent cheese from breaking down.
07 - Transfer salad to serving platter or bowl. Sprinkle remaining cheese over top and add extra cilantro if desired. Refrigerate for at least 20 minutes before serving to allow flavors to meld.
