I have had about all kinds of fruits I can grow here, but the ONLY jelly my kids like is mulberry-rhubarb. Whatever I pick (yes, pick---I don't shake the tree) of mulberries, I cut up twice that amount of rhubarb. Cook, run through sieve, and then make jelly from that juice. Mmmm Mmmm, good!!! Our rhubarb didn't do well last year, thinking I should maybe move them to another spot as they have been there over 50 years.
