I also recently watched that video, which someone had posted on FB. The shaking was visible, but I didn’t realize it could have been related to eating pawpaws until I read this thread.
I have three pawpaw trees - Sunflower, PA Golden, and an unidentified rootstock that grew after the Mango scion died. I’ll taste them once they start producing, but may need to hold off on eating in any volume until more research has been done.
