I saved wonderberry seeds, yesterday. I put a handful of berries in the blender, added water, and blended on the lowest setting. The water turned very purple! I don't think that happened last year.
Anyway, after that, I removed the fluids (and added more to clear it, and removed them again, a number of times) and poured the seeds (which had settled to the bottom of the blender) into an empty herbal tea bag to zap and dry.
