I think I figured out what I did wrong when I made Julie Sahni's phulka tonight, but not the reason they did not puff. Our guests were running late, and I decided to go ahead and roll them out. There was then about an hour pause while we had drinks etc. Then I griddled them and one of the guests (who had done this before with us, on the same range) then did them over the flame sans pan. I had thought about it before I rolled them, but figured that without yeast, it should be okay. Why didn't it work? Thanks!
