To grill the corn, rub the ears with the olive oil. Lately, I’ve been grilling my corn without the husks on, tied at the bottom, and without foil, so it takes only a few minutes. Place the ears on the grill and cook until the corn is golden or charred – whichever you prefer – turning the ears as you go. Remove them from the grill and let cool slightly, then slice the kernels off the cob.
