Krispy Kreme is rolling out a new doughnut flavor. After casting ballots, two-million Americans chose a lemon-glazed doughnut. The citrus flavor beat out blueberry, caramel and maple with about 36-percent of the vote. The limited-edition doughnut will debut this spring.After casting ballots, two-million Americans chose a lemon-glazed doughnut.
