Please forgive a non-naan-eater for butting in, but is it not the case that "Happy Chris" has demonstrated that naans can be cooked to perfection using a tava ? If so, then is it really worthwhile perserving with oven-bake methods ? Even if you do not have gas for cooking (as I do not), a propane/butane camping stove for heating the tava and singeing the naan would represent a relatively modest outlay ...
