01 - Heat a grill pan or skillet over medium-high heat. Add corn kernels and cook for 4-5 minutes until lightly browned and slightly charred, stirring occasionally. Remove from heat and allow to cool completely.
02 - In a large mixing bowl, add cooled charred corn, diced cucumbers, chopped red onion, cilantro, and diced jalapeño. Toss gently to distribute evenly.
03 - In a small bowl, whisk together sour cream, mayonnaise, minced garlic, lime juice, smoked paprika, chili powder, salt, and black pepper until smooth and fully incorporated.
04 - Pour the creamy dressing over the vegetable mixture. Using a large spoon or spatula, fold gently until all ingredients are evenly coated with the dressing.
05 - Sprinkle crumbled cotija cheese over the salad and fold in gently. Taste and adjust salt or seasoning if desired. Refrigerate for 10-15 minutes before serving to allow flavors to meld.
