We have been making heart pizzas for over 30 years using a disposable 9" red aluminum cake pan (HFA or Pactiv)) using an 8 oz dough ball. We top them with pizza sauce, Grande mozzarella and two toppings.
We typically sell around a 100 of them. Paired with a cannoli, we charge $14.
We also have a heart shaped s/s press down dough rings (Lloyd’s). Roughly 14" size. Regular menu price.
Operationally, you can fit 5 of those pans to a sheet tray and stack on top of each other. You want to pan them up in advance. Dress to order. We offer the pizza in the pan to the customer, cut or uncut, their choice. We also offer them cold with the plastic cover, to bake at home.
