At the risk of offending our Central Jersey neighbors, to distinguish a Trenton tomato pie from other tomato pies — or even pizza as we know it — is to make a distinction without much of a difference. It’s a circular, thin-crust pie where the cheese goes on the dough first and then the sauce or crushed tomatoes. According to Daily Record When the pies come out of the oven, the tomatoes might be brighter and the cheese doesn’t slide off the slices but, all melted together, it’s pizza.
But just as chicken wings and cheesesteaks are linked to Buffalo and Philadelphia even though you can get either anywhere in the U.S., there is cultural and historical significance for the tomato pie in Trenton.
