01 - Bring a large pot of salted water to a boil. Cook the short pasta according to package directions until al dente. Drain in a colander and rinse under cold running water to halt the cooking process. Set aside and let cool completely.
02 - Heat a large skillet or grill pan over medium-high heat. Spread the corn kernels in an even single layer and let them cook undisturbed for 3 to 4 minutes until lightly charred. Stir and continue cooking for another 2 minutes. Remove from heat and allow to cool.
03 - In a large salad bowl, toss together the cooled pasta, charred corn, quartered cherry tomatoes, diced red onion, chopped jalapeño (if using), and cilantro.
04 - In a small mixing bowl, whisk together the mayonnaise, sour cream, lime juice, chili powder, smoked paprika, garlic powder, salt, and black pepper until smooth and well blended.
05 - Pour the dressing over the pasta and vegetable mixture. Gently toss until every ingredient is evenly coated with the creamy dressing.
06 - Add the crumbled cotija cheese and gently fold it into the salad. Taste and adjust the seasoning with additional salt, pepper, or lime juice as needed.
07 - Transfer to a serving dish and garnish with extra cilantro and additional crumbled cotija cheese if desired. Serve chilled or at room temperature.
