Raspberries are more fragile than other fruits.
Because of their delicate composition, the keeping quality of these bramble berries is limited. Raspberries should be eaten soon after harvest and not stored for more than a day. The fragile characteristics of the raspberry make it more expensive than other types of berries. Preparation Blackberries can be washed, drained, covered and stored in the refrigerator for later use. Store unwashed raspberries covered in the refrigerator.
