Don't have the egg yet (waiting till september when I move), but I've been hanging around getting excited for a while reading all the great cooking tips. I'm going to be grilling on my Weber Kettle in about an hour--simple burgers and hot dogs, and was thinking about doing corn. Any suggestions on how to prepare corn on a grill with no temp control (i.e.--wait till coals ash over and just pray)? How long to grill? Do I need to boil beforehand? Any tips would be appreciated. Thanks.
