It's hip to be square on Flickr by beFOODled.
We bought square, thin-crust focaccias at Farm Boy and tried them out as the base for pizza. The squareness looked cool; our pizzas had a modern, restaurant-worthy shape. They were tasty, but the crust was drier and denser than the pitas we usually use. It was also harder to slice through the focaccia with a fork and knife.
Focaccia, you get kudos for being good-looking, but humble Pita, you are still in the lead. Focaccia scores points for literally delivering a square meal, but Pita is an all rounder, regularly performing well at both taste and ease of handling.
Could there be a happy compromise in the form of a square pita? Does such a thing exist? This is food for thought worthy of a Sunday morning's contemplation...
