PITTSBURGH—Sweet corn, which is plentiful at farmers markets and roadside stands in August, is often touted as summer’s best vegetable. We love it because it’s so familiar—we start eating corn on the cob with plenty of butter and salt as kids, then fall in love with it all over again as adults when we discover dishes like Mexican elote salad and corn souffle.
