Considered by many the most intensely flavored member of the berry family, the raspberry is composed of many connecting drupelets (individual sections of fruit, each with its own seed) surrounding a central core. There are three main varieties — black, golden and red, the latter being the most widely available. Depending on the region, raspberries are available from May through November. Choose brightly colored, plump berries sans hull. If the hulls are still attached, the berries were picked too early and will undoubtedly be tart. Avoid soft, shriveled or moldy berries. Store (preferably in a single layer) in a moistureproof container in the refrigerator for 2 to 3 days. If necessary, rinse lightly just before serving. Raspberries are very fragile and are at their best served fresh with just a kiss of cream. They also make excellent jam. Seedless raspberry jam is available commercially. The berries contain a fair amount of iron, potassium and vitamins A and C.
