This recipe comes to us from Mark Bello of Pizza a Casa, a pizzamaking school and pizza-supply store in New York City. Bello notes that for the final product, you should use coarsely ground pork with a meat-to-fat ratio of 3:1. Par-cooking it first in patty form (rather than loose in the pan) helps it retain juiciness and creates a large mass that you then break up into grape-size chunks for your pizza. Cook to just above pink. The seasoning measurements here are for 1 pound of ground pork. Size them up proportionally if you're making larger batches.
