I can bring baking powder if you need some. Got an order in for tomorrow to be delivered whilst I'm at work! If you don't use baking powder, the bannock won't rise. You'll get a roof tile instead of unleavened bread!
Roof tile is probably my style! but cheers if I can nick some baking powder as Id like to have a go at bannock. Im not going to have time to go to the shops in the morning, unless the shop near the campsite sells any, but it was fairly small so its doubtful. Im sure flour milk and baking soda make something edible anyway.
