Boysenberries, hybrids of the raspberry and blackberry, are sweet, large, reddish black berries, which are in season during the late 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.
For other berry varieties, see blackberries, blueberries, cranberries, fraises des bois, gooseberries, loganberries, raspberries, and strawberries.
