How to Make It
Place corn in a large pot, and cover with water. Add butter and 1 tablespoon of the salt in pot; bring to a boil over high heat. Reduce to medium-high, and cook 12 minutes. Turn off heat, and let corn stand in water 5 minutes. Drain, and place corn on paper towels to dry.
While corn cooks, stir together mayonnaise, sour cream, lime zest, lime juice, and remaining salt in a small bowl. Process Cheetos in a food processor until finely ground. Place crumbs on a shallow dish.
Brush mayo mixture evenly on each piece of corn; roll in Cheetos crumbs to coat. Serve immediately.
