Tempeh Starter Raprima. (Rhizopus Oligosporus ) 2 bags 1 Kg.
I ordered this about 8 months ago from Indonesia. It took about a month to arrive and was in perfect condition. It lasts forever in the freezer.
The North American sellers are a complete rip off. I make a batch of tempeh about every week or so.
