While dumping the contents of my memory to this post, I should note that the willow water was prepared
before prepping and cutting the corms. I just wanted to point that out, as I didnt want the corms oxidising and drying out before steeping in willow water.
corrections and better explanatories added above,
FYI, the 'blue namwa' was listed in thailandplant.com as
Musa (ABB group) 'Kluai Nam Wa Naun Jun' BLUE JAVA ICE CREAM Banana Plant. Now they do list regular namwa separately, so I'm not sure if this is a blue namwa or just their name for a blue jave. Only growing and examination of fruit hands will tell. So a 2 year wait at least. I will be looking for knuckles or palms (hand palms).
