As many a city dweller or person without a backyard can lament, easy, frequent grilled food is a rare treat in the summer. But, in the air fryer, fresh corn doesn’t have to be such a rarity. Brushed with a little butter, it chars lightly and cooks up tender and crisp at the same time. It’s perfect eaten right off the cob, but even better in this side dish reminiscent of Mexican street corn, composed of the cob’s shorn kernels, copious cilantro leaves, and a spicy mayo.
