[Sarah]

A dense, poorly-leavened bread that travels well, making it a great, tasteless vehicle for calories. It is often used by tradidtional campers who canoe and portage for weeks at a time, as it doesn't fall apart when wet, and can be cooked in the heat of a dying fire for lunch the next day. That allows the campers to unwind instead of cooking, but adds to the density of the food.

Must be an old word for cake, because bannock-hives are 'swellings' from eating too many bannocks (i.e., fat rolls).
