While black-raspberry ice cream may be the extent of your black-raspberry knowledge, these sweet and succulent berries (not to be confused with blackberries) do exist in the primitive form – you just won’t find them in most grocery stores.
Scout out your farmers’ market for deep violet raspberries hiding among the typical red varieties. While blackberries (a completely different variety of berry) are easy to come by, I only know of one local farm that grows black raspberries in my area. They’re only available for a short time (usually mid-June to late July). Use them for any raspberry recipe – trifle and salad dressing are just a few favorites. They make an incredibly special and refreshing granita.
