I’ve got the dandelions, birch bark, and wild cherry bark for you Malgus.
I made my 1st batch of rhubarb jam and it seems to have come out OK. Most recipes call for adding strawberries, blueberries or some other fruit but I figured none of those other items are locally available this early in the season and so if in the future I am to use the rhubarbs on a standalone basis, then plain rhubarb jam it is. I followed the recipe exactly but I think next time I will try it using less sugar than it called for.
