A very interesting sounding book. I'm gradually learning and figuring out how to bake without grain. I've been making my own baking powder from a recipe found on the web. Yes, I was curious as to why you needed a starch in the powder. And most commercial baking powders have thing that I don't do well with. I also have used many recipes with sour milk with baking soda. It will be interesting to learn more of your suggestions and tips on baking. Congratulations on your book.
