6+ ears of corn the amount depends on how may folks your feeding.
aluminum foil if your not leaving it in the husk
1/2 Tbsp of salted Butter per ear of corn
Salt and Pepper to taste
1 tsp of any other spice you feel the need to have.
If your corn is in the husk and you are going to grill it in the husk peal back the husk and clean the silks off the corn then pull the husk back in place. If your not going to keep the husk on pull it off and clean the silks and set the corn to the side. Once all ears are shucked wash the ears and pat dry with a paper towel. Allow the butter to soften and take each ear and "butter" it then apply salt, pepper and spices (garlic powder or cloves, onion powder, season salt, lemon pepper, chilli powder or any other hot peppers.) If you are cooking in the husk fold it back over the corn and tie in place with kitchen twine, if you are using foil wrap each ear tightly.
Fire up the grill and cook each ear for around 10 to 15 minutes turning frequently so that all sides are touched by grill heat. When you remove the ears the kernels should have a toasty brown color in parts of it.
