Raspberries, because they are so perishable, should be checked carefully for signs of mold. Perishable is the key word. Berries can turn soft, mushy and moldy within 24 hours. When you get a box home, turn out the berries and check them over. Spread on shallow plate or pan, top with paper towels and then cover with plastic wrap.
Most berries last only two days.
Berry flavors are at their best at room temperature, so if possible, take them out of the refrigerator for an hour before serving. Always wash berries just before using, and keep stems on strawberries until ready to serve. For longer storage, many berries freeze well. Place berries in freezer until solidly frozen, then transfer to heavy plastic bag. They'll keep for 10 months to a year.
