01 - Heat a grill pan or skillet over medium-high heat. Add corn kernels and cook for 4-5 minutes until lightly browned and charred, stirring occasionally. Remove from heat and let cool completely.
02 - In a large mixing bowl, add cooled charred corn, diced cucumbers, chopped red onion, cilantro, and jalapeño. Toss gently to distribute evenly.
03 - In a separate small bowl, whisk together sour cream, mayonnaise, minced garlic, lime juice, smoked paprika, chili powder, salt, and black pepper until smooth and well combined.
04 - Pour the creamy dressing over the vegetable mixture. Use a large spoon or salad tongs to toss gently until all ingredients are evenly coated.
05 - Fold in the crumbled cotija cheese, being careful not to overmix. Taste and adjust seasoning with additional salt or lime juice if desired.
06 - Refrigerate the salad for 10-15 minutes before serving to allow flavors to meld. Serve chilled as a side dish or topping for tacos.
