Strawberries have the most vitamin C of the berry family. Strawberries have been known since the time of the Greeks and Romans. They are at their peak from spring to midsummer, are plump, red, juicy, and intensely sweet when ripe. Select unbruised, slightly soft berries with a deep color and an inviting fragrance. Store unwashed and loosely covered in a single layer on a tray or platter lined with paper towels in the refrigerator for a few days
