Look forward to your photos UF
Anyway I had a go at naans today. I made the dough yesterday and i knew from the onset the dough wasn't up to scratch but as a trial it would do. Having a steel liner I thought that this might lend it self to naans for sticking and how right I was (for a change).

Fired up both burners and let it heat up for about 10 mins. It was hitting nearly 400 degrees C so I turned the burners down a bit and off set the lid. Made a 1/2 size naan and wet it once on the cushion. Straight in and it stuck straight away.

Waited till it looked cooked and removed it with my bbq tongs and big bbq knife. Bottom was burnt a bit due to it being to hot and it wasn't great due to the poor dough, but the main thing was it cooked.
Had a bit of a soot build up due to the bottom burner being to hot and some crap burning of the stones. A quick wipe with a damp cloth sorted that but I still need to do other side once cool.
Next one, I turned both burners down waited a bit then in with the naan.

This one came out much better although still biscuity due to the poor dough I made. Heres a photo of the base although it looked a bit different in colour wise in real life.

Overall happy with the results that it can be done, now just have to make some dough without rushing it

and have a bit play with the gas knobs and the temperature gun.
