There is a ST Lucian man in Punta Gorda called Gomier who makes it. I am sure that he would put some on Tropic Air for you to get picked up at the SP airport. Visit www.plenty.org
and follow the links. ([email protected]
Incidentally, PLENTY is an excellent organisation involved in sustainable argriculture, low cost medical care, etc in the Belize and several other developing countries.
I would also seek out the Chinese community as they produce it.
