Bread-Bakers v098.n048.5

        The baking powder formula that works for me, & in all recipes from
about 1945 on, is very simple. 
        Thoroughly mix equal parts of baking soda, cream of tartar & starch.
The starch can be arrowroot, tapioca, potato, rice, or whatever you can eat
or have at hand. I usually use tapioca starch these days. If you remember to
convert when using it, you can even leave the starch out, which I tend to do
for the cabin & camping.
        I hope this helps someone wrestling with an allergy or an empty tin.
