In a skillet-  Use a cast iron skillet to get the same charred effect. Cut corn kernels off the cob and add to a hot greased cast iron pan. Roast the corn for 5-6 minutes, stirring continuously. You will begin to see charred spots. On A Stovetop Grill- You can also use a grill pan. Heat grill pan, add corn on the cob and cook until it looks charred. Turn as needed to char all sides.
