3 T. butter, melted (I zapped mine in the microwave for about 30 seconds - watch it carefully)
Juice of ½ lime
1 tsp. chili powder
½ tsp. garlic powder
½ tsp. salt
Freshly ground pepper
Method
Preheat oven to 450 degrees F.
Tear off 3 pieces of aluminum foil large enough to wrap a single ear of corn. Lay each ear of corn on a piece of foil. (I like to cut each ear into 3 pieces to make eating them a bit easier.)
Mix together the melted butter, lime juice, chili powder, garlic powder, salt, and a few twists of freshly ground pepper. Brush each ear of corn thoroughly with the butter mixture.
Wrap each ear of corn in the foil, place on a baking sheet, and roast for 20-25 minutes. Carefully unwrap - watching out for steam trapped inside the foil - and enjoy!
