Blackberry, juicy, lustrous purple-black berries that are at the peak of season in summer. 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. Substitute berries frozen without syrup when fresh are not available.
For other berry varieties, see blueberries, boysenberries, cranberries, fraises des bois, gooseberries, loganberries, raspberries, and strawberries.
