Cook the Corn:
In a skillet, heat olive oil or butter over medium-high heat. Add corn and cook for 5–7 minutes until lightly charred and golden, stirring occasionally.
Make the Dressing:
In a large mixing bowl, whisk together mayonnaise, sour cream, lime juice, garlic, chili powder, smoked paprika, salt, and pepper.
Combine:
Add the warm corn to the bowl and toss until evenly coated. Stir in chopped cilantro and most of the cotija cheese.
Garnish & Serve:
Top with remaining cheese, extra chili powder, and a squeeze of lime. Serve warm or refrigerate for 30 minutes for a refreshing cold corn salad
