Step 1

Heat a gas grill to 400 degrees F, or prepare charcoal for a charcoal grill.  Husk the corn.

Step 2

While the grill is heating, mix together the sour cream, mayonnaise, cilantro, garlic, chipotle pepper, lime zest, lime juice, and 1/2 cup of the cotija cheese.  Taste and season with salt, if needed.

Step 3

Grill the corn by placing the husked corn directly onto the grill grates.  Grill for about 10 minutes total, turning every 2-3 minutes until the kernels are lightly charred on all sides of the cobs.  Remove from the grill to a large baking dish or plate.

Step 4

Using a brush or spoon, slather each ear of corn with the sauce, then sprinkle with remaining crumbled cojita cheese.  Sprinkle with additional chipotle pepper and chopped cilantro and serve with extra lime wedges, if desired.
