The grill is working out nicely and dinner was delicious last night! Oh my goodness was it good! I tried this with the corn and it worked out nicely:
Fresh lemon juice
Combine butter, lemon juice to taste, and garlic in a bowl, microwave until butter is melted.
Remove husks from corn and place corn on grill (I put mine on the little "warming rack" but you could probably put it on the cooking part too). Turn corn and rebaste every few minutes until it looks a deep yellow. Enjoy!
Other ideas for serving: themed spices - try curry, red pepper flakes, pesto, or chili powder melted in with the butter for serving with different types of meals...
