This morning, at the construction site of his new Cane Rosso pizzeria in Deep Ellum, Jay Jerrier took delivery of an oven that’s going to change the way Dallas thinks of pizza. There are only a couple dozen true Neapolitan ovens in the United States. This is the first one in Dallas. Jerrier has been waiting for the thing for months, following its construction in Italy and its long voyage across the sea. When he got it this morning, he had to fight the urge to rip off the shrink wrap. His general contractor told him to leave it on so the shiny red oven wouldn’t get dirty from all the dust kicked up by the workers who are finishing out the space. An authentic Neapolitan oven, so you know, has a much shallower dome than other pizza ovens, giving it better heat-conducting properties. This morning Jerrier also got a special dough-mixing machine that he says will make a big difference in his crusts. He’s shooting to have the place open February 1.
