Bacpacjac,
Thank you for this post, I have been wanting to make some Bannock for a few months now.
I also want to thank you for showing the correct way to bake in a cast iron skillet (look for Bannock Bread on youtube and you'll know what I mean) over a fire.
I have seen youtube videos showing how to make Bannock in a standard G.I. canteen cup. IIRC the person doing it burned his bread.
