Loganberries, hybrids of the blackberry and raspberry, resemble long, shiny raspberries but have a sharper flavor. They are available in early to midsummer. 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, boysenberries, cranberries, fraises des bois, gooseberries, raspberries, and strawberries.
