The key to making this Mexican street-food and market-vendor snack is to char the corn on the grill and then brush it with mayonnaise so that the cheese, cilantro, and chile powder adhere to the kernels.
- 4 large ears corn, with husks still attached
- 1⁄2 cup mayonnaise
- 1 1⁄2 cups crumbled cotija cheese
- 4 tbsp. minced fresh cilantro
- 4 tsp. ancho chile powder
- Kosher salt and freshly ground black pepper, to taste
- 1 lime, cut into four wedges
