I have been making a lot of whole wheat pita bread using Atta flour and it has been turning out great.  Then I heard about 00 flour from Italy and was wondering what the difference between them was and if they are interchangeable. 
Thanks.

Perhaps if anyone else has additional experience or info they will chime in

These two flours could not be more different. They both make delicious food though. Atta is coarse and Italian 00 is so very fine, it’s like silk. I’d use the 00 in flatbreads, like pizza. Course, you could try it and see. I make pita with bread flour, AP flour, whole wheat and atta! You have to adjust the recipe a bit depending on the flour you use. Just add more flour or water until it behaves when you roll it out.
