Should i use All Purpose Flour or Bread Flour? Doesn't specifcy.

I would use all-purpose for this recipe; it doesn't need the high-gluten development of an airy artisanal bread.

You could use either, but AP is probably closer to the 00 flour that would likely be used in Italy- it should be a fairly strong AP, like King Arthur (stay away from bleached; it tends to be very low gluten.
