1 large egg white
1 tablespoon water
1 cup packed fresh mint leaves
1⁄4 cup super fine sugar (you can make this by putting sugar in food processor for a few minutes)
In a shallow bowl stir together egg white and water. Brush onto leaves, dip leaves in sugar. Let dry on a rack for at least 6 hours, store in an airtight container at room temperature. Leaves can be made a day in advance.
