Oh good, I'm stoked if this helped a little!
Before I answer, I just wanted to clarify - I'm not sure I understand what you mean by the 'bark' of the bean... Do you mean like the pod? Or the skin around the bean itself? Let me know! :)
Always feel free to keep reaching out with questions!
Hii. How was your day?
I meant the skin around the bean. 🙂
