Step 6: done
It took almost 2 days for the globs to dry out completely. The ones on the wax paper took slightly longer, but they did come off the paper easier than the other ones came off the tray.
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.
