For human consumption it's available in some health food stores in California (and maybe elsewhere) but the easiest thing, Mare, is just buy a whole potpaya

at the local grocery store and put it in a blender with a little water and make your own.
California ... I'm lucky if I leave the county. Okay, the hubster will be sent out to buy a whole Potpaya. He'll probably be looking for a plant of sorts ... but I'll print a picture off the internet for his shopping-by-photo. We have a gallon of Vodka left from T'Giving too (for the owner and Trainer, that is). Thank you ... I'll post on our progress.
