Buying and storing tips

Look for plump, shiny blackberries; most varieties will have a core to which the drupelets are attached, but this does not indicate that they are immature. If the berries have a rich aroma, they are ripe. Check the bottom of the container to make sure it has not been stained by crushed or moldy fruit. Fresh blackberries are best used immediately, but they may be refrigerated in a non-airtight container lined with paper towel, preferably in a single layer, for one to two days. They should be washed only just prior to use.

To prevent blackberries sticking together when freezing them, place them on a cookie sheet so that they are not touching each other, and then in the freezer; once frozen, put the berries in a sealable plastic bag.
