Dehydrate your tomato skins (when canning) and turn it into tomato powder! You can do this with your apple peels too! Add the powder to any kind of apple cake or pie, etc and taste the extra difference!
I like these because they use xylitol, which is actually good for your teeth (the neato and ever-helpful guy at the health food store told me about it when I got my wisdom teeth out). And you can make it any flavor. I love this website, the burlap bag :)..
Homemade Baking Powder Recipe. I have been making this for years, equal amounts of baking soda and cream of tartar. It's been working for me very well. I don't use corn starch. I put it a well sealed jar with some dried lima beans to absorb any moisture, shake the jar before I take some out. Much healthier to make your own, and cheaper! I buy the cream or tartar organic, a pound at a time..
