Baking powder

A crude form of baking powder can be made in the bush. If you can find a Quaking Aspen tree cut a few branches off of the tree and burn them. The ash from the fire will be a fine white powder. This can be substituted for baking powder. Baking powder can be used to make bannock which is simple bread. The Quaking Aspen can be identified by a white powder that forms on the outer bark.
