I am the recipient of a HUGE box of plums, freshly picked from a co-worker's tree. They are big, purple, and really good eating. Since I have at least 25 lbs. of these I thought I would make jelly, but all the recipes call for tons of sugar and also for added pectin. It has been several years since I have made jelly, so I'm a bit hazy on how flexible I can be with quantities of sugar and pectin. Do I really need pectin? Is there an alternative?
I would appreciate any suggestions and/or recipes, even some unconventional ideas for combinations of plums and herbs, etc.
