I have been inspired to try again by The River Cottage Family Cookbook which
The recipe intrigued me as it uses orange juice in the first stage - I also love this book as it explains a bit more about the process and the reason for using certain ingredients (such as organic flour and mineral water).
So I mixed and ended up with this which needs to be left in a warm place for 24 hours.
I'll just have to wait and see if it is more successful than my last attempt. (I should confess though, that to be on the safe side, I followed Hugh's slightly cheaty instructions and added a pinch of dried yeast to the inital mix.....)
