The end product is crunchy and tasty. The raisins retained their chewiness and sweetness which is good. This is good travel food. I'll take some on a bike trip. It should keep pretty long, but again I haven't waited long enough to find out.
I would assume that most of the bacteria die without having moisture, so I would hesitate to call this food "probiotic."
-I made one batch with a mixture of rye flakes and oats. It came out tasting like rye bread. I'd like to try that again, adding caraway seeds, onion, and garlic.
-Maybe it could be done with ground up oat groats.
-I'm sure it could be done with several other grains.
