I hope I didn’t misread about the bloating not working for you. We use a footed rack (we purchased it in Indiatown – it’s round and fits over top of the stove burner) to make the chapati puff up. We start the cooking the way you do on our carbon steel tava (looks like you have one of those) looking for little bubbles and uniform lighter colour then we use tongs to move the chapati from the tava to the rack that is set over med high to high heat and move it around on rack so it puffs all over; sometimes little holes appear to deflate it but clever use of the tongs can seal the hole.

Very nice!
