This bread is really good - it actually tastes a little bit cheesy, even though there isn't any cheese in it. Mine didn't puff up either, but maybe that's because I used only chana flour (I'm not quite sure what chapati flour is). It also takes a bit of practice to get the balance between the wet and dry ingredients. I didn't use a rolling pin...I found that it was more effective to spread a bit of flour on the counter and flatten it with my hand. Anyway, I can see this becoming a staple for me. It's good with all sorts of other things besides Indian curry.
