If just making one meal’s worth, consider using a peeler to make ribbons. They cook almost instantly in a single layer at a time. I prefer thicker planks since I’m usually making lunches for the week and the planks hold up better.
I don’t bother with soaking but do corn pretty similarly. One thing I can recommend is to lop all but about a half inch of the stem. Then, remove the outer couple layer of husk and trim off the exposed silk at the top and any stray bits of husk. The inner husk is a little wetter and less prone to burning. It still gets a little singed and picks up that smoky flavor.
I also get the corn on the grill first and sort of arrange it around the outside of the grate. By the time the brats or chops or chicken and zucchini or asparagus is done, the corn is getting close.
I like to keep the stem long. It’s like a handle, and you can peel back the husk and silk in one piece. If you leave the outer husk on, you can cook the corn while the grill heats up without over-cooking it. I leave it on the top rack so it stays warm while I grill the meat.
I’m late to saying this, but this is the correct answer when grilling corn. I like the elotes in a cup places, but nothing compares to doing it yourself or going to a place that prepares the cob on a grill, then mayos, butters, spices and cheeses it up afterward. Even if I’m not going to completely dress the corn, I want it a little scorched.
Part of it is that I primarily use a smaller charcoal kettle, a 18" Weber, so keeping the ears compact helps keep the mainstage clear. But I also think it make the ears easier to peel. That 5/$1 season for sweet corn will be here soon enough, give one a try.
Has this been mentioned yet? Take some potatoes, wrap them in metal foil, and bury in hot coals. Wait for them to roast, an hour or more until they are done.
(Yes, I realize this is technically not a “barbecue”)
I will try your method next time I grill corn (even though corn is still 2/$1). I sometimes use a Weber charcoal kettle on camping trips, but your method should be good for cooking on a campfire too.
I hit the jackpot at recycling with six metal coffee cans. I’m set for life. I’m debating whether it’s worth the trouble to drill some air holes. Seems like you would get maximum air flow without any. What say the Dope?
