Am I missing something here? Roti is very easy to make. I am a terrible bread-maker, but Roti (and flatbread) is the one thing that doesn't intimidate me. The fact that there is no yeast to work with is always a bonus when it comes to bread-making for novices.

I watched the promo video linked by the OP, and I admit, it was very impressive, but it also underscored its simplicity, when it is basically just equal parts water and flour plus a very hot pan.

Here's a tip that I got from an Indian friend of mine: She uses equal parts flour and natural yoghurt (instead of water). Make a dough, and leave it in a warm place for half an hour. Roll them thinly and put in a very hot dry pan. After a minute, bubbles will form on the surface, then flip it over for another minute. And you're done!
