Hi Josh,
Thanks to George's confirmation, I decided to give my granite block a try. I set my oven to 250c and placed my block on the middle shelf. I let this heat up for a good hour.
Although I really need to brush up on my naan making skills, I think for a first effort, they turned out really good.
I think next time, I will roll the dough out to about 5ml thick, as I went too thin this time, and the naans turned out crispy in places, still, the taste was bang on.
Many thanks Josh, good recipe.
