Ripe fresh berries are naturally the best choice for this pure fruit fondue. Out of season, frozen berries can still make a memorable sweet tart dessert, but be sure to choose unsweetened, individual quick frozen berries. For dipping, offer shortbread or crisp gingerbread cookies, bite size cubes of pound cake, chocolate or hazelnut biscotti, apple or nectarine wedges, or chilled cubes of mild cheese, such as Brie or Havarti.Unknown source
