I made a batch of whole wheat chapati, which confirmed my suspicion that brick/adobe ovens really are very well-suited to this type of unleavened flatbread. Coincidence? I think not.
I have battled in conventional ovens to make these little buggers work out. You end up opening and closing the oven door every ten seconds to see how they are doing and its hard to get the bread to get that nice mottled browning that comes from the intense retained heat and adds to the flavor. In an adobe oven its a piece of cake (though that seems a strange idiom).
These recipes are as simple as can be. (Here is another) Mine was something like 3 cups whole wheat flour (I used King Arthur) to a cup of water and some salt per 6 breads. You mix the stuff up, let it sit for an hour or more, divide into balls, roll 'em thin (8 inches, or so) and then throw them into a hot oven with tame fire burning in the back. Within a minute they puff up. You turn them once, pull 'em out and brush 'em with clarified butter.
Eaten shortly after baking they are incredible. I can honestly say that for some reason, I never really enjoy the flavor of whole wheat in any other bread the way I do in a hot chapati. You can reheat them the next day, but they are never quite the same.
