Hi Paul
I make my own bread using a Panasonic SD255 which I've found excellent and well worth the cost. It comes with a good range of recipes including ones for French bread that have no added sugar plus gives details for using olive oil rather than butter as the fat. It copes with rye flour too plus allows me to add seeds through a drop down tray which also lowers the GI
Strong white, brown, wholemeal flour is readily available in supermarkets and the larger ones have more varieties too. I've had to go to my local health food shop for rye flour though although I understand that larger branches of Waitrose stock it. You can also just add water to ready prepared bread mixes and get a result in two - three hours
The downside - resisting the temptation to eat too much of the newly baked, lovely smelling stuff!
