Those look excellent! The Naan we get here in the US doesn't usually have the huge bubbles like seen in other recipe postings. I had to run into the city so I was lucky enough to stop at the Indian grocery again on the way home and talk to the shop owner. He said he surveyed his restaurant owning friends and they don't add much to the dough (just like the recipe here). I think he said some don't even add salt! They definitely use just milk, no yoghurt, and only one of the restaurants said they use any egg either.
With the weather turning pretty nasty here, I'm not sure when the next tandoor session will be, but I will be trying SP's recipe and I think I am going to try it with and without the egg and see what happens and how both versions compare to the restaurant-style naan I've had.
At a certain point, I think one will only get so far until the recipe is right, tandoor or not. I think this is going to be another big jump in getting there.
