Here’s the easiest way to barbecue corn on the cob.
If you've purchased corn from a farm with all the husk in tact, follow these steps. If it's from a grocery store usually only half the husks are on and half the corn is exposed, so skip to the soaking.
Pull down the husks to the base of the cob without tearing them off, you just want to open it up to expose the cob and the fine silks. Remove the corn silks and discard.
Fold the corn husks back up to cover the cob and soak the whole thing in water for at least 30 minutes.
Grill on the upper rack of the bbq or the outer sides where it isn't as hot for 10 minutes. Once the corn turns bright yellow and you start to see some caramelized brown spots, the cobs are done.
