Interesting. As a vegetarian, cutting up the scoby was gross - as it reminded me of raw chicken. And I couldn't really get away from that to really enjoy the end result.
But if someone else made it and gave it to me - I would assume that it was just a homemade gummy candy. Nothing nefarious (or however you spell that).
My husband, who usually eats whatever I tell him to - couldn't try it either. It's totally a mental thing though - cuz the actual candy is pretty normal/good.
If you try it, I'd recommend some flavoring (ginger/lemon seems to be the recommended) - as it's very bland.
