I lived in Pittsburgh as a child and one of the things we looked forward to this time of year was Mama’s corn. Once summer arrived, a little farm stand called Mama’s sat at the top of the hill near my grandparents’ house. From the second it opened every season, it overflowed with the sweetest corn you could sink your teeth into. As soon as the public swimming pools and Dairy Queens opened their doors Memorial Day weekend, the next question on our lips was, “Is Mama’s open yet?”
