That said, what's the danger of arranging the tiles in a "+" shape? I guess a greater chance of catching the peel on the edge of the tile. Some cult we have going here.
If you do the math correctly then you'll see why omid did "+" instead of "X".
Thatís right, the geometric limitations compelled me to implement the "+" configuration instead of the "X" configuration, although my preference was to implement the latter. The internal diameter of my oven floor is shorter than the width of the uncut biscotto tiles placed together side by side. I could have done the "X" configuration, but then I would have ended up with 6 or 7 cut pieces instead of 5 pieces. Also, since I wanted the oven door to go passed the chimney in order to maintain the heat inside the oven chamber, I had no other option but to adopt the "+" arrangement. There is more to this, but I think you get the gist of it.
In my mind, there is no question about the "X" being more practical than the "+" layout, especially in a large oven where multiple pizzas are baked at a time, but my oven floor is very small (smaller than the floor of the "Pizzone" by Pizza Party) and can handle only one pizza at a time. Good day!
