Corn Grilled in its Jacket

Directions

1. 1
   Preheat the oven to 350 degrees F.
2. 2
   Place the corn, still in its husks, directly on the oven rack and roast for about 20 minutes until the corn is soft when you press on it.
3. 3
   Take the corn out of the oven and let it cool a little until you can handle it, or until you're ready to serve.
4. 4
   When you're ready to eat, place a large grill pan on 2 burners over medium-high heat or preheat an outdoor gas or charcoal barbecue and get it very hot.
5. 5
   Take a few paper towels and fold them several times to make a thick square.
6. 6
   Blot a small amount of oil on the paper towel.
7. 7
   Then carefully and quickly wipe the hot grates of the grill to make a nonstick grilling surface.
8. 8
   When the grill or grill pan is hot, peel down the husks from the roasted corn and pull out the corn silk.
9. 9
   Then tie the husks in a knot so you can hold on to the knot like a handle.
10. 10
    Char the corn on the grill or grill pan, turning, until the kernels are slightly blackened all around and start popping, about 6 minutes.
11. 11
    Brush the corn with mayonnaise, and sprinkle with the Parmigiano and a little cayenne pepper so it's nicely coated.
12. 12
    Serve with lime wedges.
