Yes this was the sort of thing I was thinking of .. but I was thinking of using kefir whey or kombucha as a starter..
But I guess sourdough starter sounds a good way to go.
Hi
I'm interested in this also .. I see hodmedods do a fermented whole grain barley.. it looks interesting but I can't find any info on how it's done...people seem to be eating it direct from the jar without cooking so I'm guessing it's cooked.
