We put in pumpkin seeds cos we had some lying around, they didn't stick in the dough very well, but when it was all baked, it was okay.
I did the kneading myself, took ages, I think I got the knack.
I reckon I'll try making my own bread at home, and add all the usual random stuff. Maybe branch out into experimenting with different flours, rice, buckwheat, potato and pasta flours. Could be exciting.
