4 ears of corn
1/2 cup mayonnaise
1/2 cup Cotija cheese (Parmesan will work if you can't find it)
2 limes, cut into wedges
2 tablespoons chili powder
1 tablespoon cumin
Prepare a grill or grill pan with high heat. Keep corn in husks, or remove one strip of husks. Place directly on grill. Cook for 10-15 minutes, turning occasionally, until husks are well blackened and the kernels are bright yellow.
If serving on the cob, remove husks and slather each ear with a generous spoonful of mayonnaise. Add the juice of one lime wedge per ear, followed by a pinch of salt, a healthy sprinkle of cheese and a light dusting of cumin and chili powder.
If serving off the cob, cut the kernels off of each ear. Place into a jar or small cup and top with remaining ingredients.
If you prefer, serve the corn with the toppings on the side and let everyone dress their own.
