I'm sure there are infinte varieties of cranberry relish on our Thanksgiving and Christmas tables. With this one I wanted to evoke a traditional New England flavor. Fortunately I can buy cranberries fresh from Cape Cod. If you freeze cranberries upon purchase they will work fine. Raspberries were added for sweetness, without overpowering the cranberry, but you could substitue other berries. The flavor of this relish is intense so adjust the sugar to your taste.
