Husband brought us in each a ripened blackberry. Sweet, but just a bit tart. I will have to watch them day by day now to pick them at the right time. We have them growing here wild, and I remember growing up with my parents picking so many bucket fulls of them to use in cobblers, jams, etc.
Years ago I had a neighbor who grew rhubarb, and would can hers up too into jams, but also make rhubarb pie.
