charlize SG Because calling it "Circular dough bread with unexplained hole in the middle" is bad marketing and probably won't sell.
matrixeg SG to put your bloody finger in it so that easier to hold w/o your hands touching the toppings. Also to save on dough and toppings by having an empty space in the middle (bakers are quacks)
sinicker SG easier to hold. can put ur thumb in the middle and ur index finger on the outside. den can hold easily... k, talk crap. can fry faster.
