D.C. Pizza Master,
Americans respect tradition, even in Italian pizza making, but they rarely feel bound by it. They don't mind change. In fact, they welcome it. Pizzas that are not round, that is, of irregular shape, are viewed as being more homemade, rustic, charming and with more character. Famous restaurants like Al Forno in Providence and Pepe's in New Haven proudly feature pizzas that are of irregular shape. Pat Bruno, a writer for PizzaToday, in an article a couple of years ago, predicted that the trend in pizza shapes was as follows:
"The shape of pizza. Look for more pies to be rectangular or oval in shape.It doesn't hurt to show something a little different now and then. (In one of my pizza books I have a pizza with a hole in the middle; it never caught on, but who knows?). Also, you might want to think `pie are square.' A lot of pizza places in Italy do pizza ai metre, or pizza by the meter, since it is cut into a length determined by the eater. Something to think about."
