I picked and froze the last of our jostaberries the other day, jostaberries being a cross between a black currant and gooseberry. Our oldest bush and the parent plant of numerous others is now around 4-5 years old and starting to produce fairly well. I think we picked almost gallon off it this year. We have many more "starts" ranging from 5 months to 3 years old and are excited at the prospects of reaping ever increasing harvests going forward.
Perhaps my favorite thing about this plant when compared to our gooseberries and currants is that the fruits, in our garden, ripen much later helping us to avoid any problems with currant flys that so often plague the latter two. The flavor can best be described as sweet and tart, I have a feeling we will enjoy using it in various recipes in the future. It is not as tasty as a goosberry but if you take into consideration it's lack of pest issues the flavor gap becomes less noticable. One other thing I like about this particular plant is that the fruits do not fall off everytime the wind blows like our currants tend to do. The berries are firmly attached, almost too firmly.
