Matt, it really does depend on your particular grill. I can do this with pretty high heat on my grill–that may not work for you if your grill runs hotter than mine. I’d suggest taking an ear or two of corn and experiment with what temperature works best for you.

Great! That does help a lot, doesn’t it? I also found that putting a couple of ice cubes in foil dinners helps those as well. The ice cubes melt and turn to steam, and are much easier to put in than trying to put some water into the foil packs.
