Step 1

Preheat oven to 350 degrees F.

Step 2

Place the corn in its husks directly on the oven rack and roast until the corn is soft when you press on it, 30 to 40 minutes.

Step 3

While the corn is roasting, combine the butter with the chili powder and lime zest.

Step 4

Peel down the husks and tie in a knot to use as a handle while eating. Rub the corn with soft butter mixture, and garnish with a lime wedge. (This roasting method produces the sweetest corn I have ever tasted.)
