- Heat oil in a large non-stick skillet over high heat until shimmering. Add corn kernels, season to taste with salt, toss once or twice, and cook without moving until charred on one side, about 2 minutes. Toss corn, stir, and repeat until charred on second side, about 2 minutes longer. Continue tossing and charring until well charred all over, about 10 minutes total. Transfer to a large bowl.
- Add mayonnaise, cheese, cilantro, jalapeño, lime juice, and chili powder and toss to combine. Taste and adjust seasoning with salt and more chili powder to taste. Serve immediately.
