Easter is, naturally, a big holiday in Italy and one of the traditional foods served in Umbria, Marche, and Tuscany during the season is Pizza di Formaggio or Crescia al Formaggio. Despite the image this name evokes in America, this pizza is actually a yeast-leavened bread, heavily flavored with grated Parmigiano and Pecorino cheeses and makes a great meal paired with some good salami or ham and a glass of white wine!
A word on cheeses:
Pizza di Formaggio can have a mild or strong flavor depending on the proportion and type of cheeses used. The amounts and ratios are a matter of preference, and vary from one prized family recipe to the next.
Just as champagne refers to a wine grown in a very specific region of France, Parmigiano refers to a very specific cheese produced in specific region of Italy. This cheese is the only one allowed to use the name “Parmigiano Reggiano”, so if you find it by this name in your local grocers it will by definition be imported. Reggiano has a very strong, nutty flavor with a definite sweetness and a grainy texture.
Another import, Grana Padano, has a similar profile to Parmigiano yet produced in different regions, mostly Lombardy. It has a smoother texture, and its flavor is not quite as strong as Reggiano. It’s also cheaper, both in Italy and exported and is a frequent stand-in for it’s bolder cousin.
Other “parmigianos”, domestic and foreign produced, are generally less complex in all senses of the word.
Pecorino is a sheeps-milk cheese and there are distinct varieties in different parts of italy. In the US, we generally associate Pecorino with the specific aged variant known as Pecorino Romano, or just “Romano”. Pecorino Romano also has a strong flavor, though less nutty and brighter than Parmigiano.
Traditional Pizza di Formaggio uses these cheeses in various proportions, but given price and local availability, it may be hard to get your hands on either of them. You can experiment with other cheeses such as Manchego Viejo (a spanish cheese similar to Pecorino), Asiago (fairly common in the US, much sweeter than Parmegiano but with some of the same nutty elements)
The most critical rule is that you avoid the green-can offerings and anything pre-grated. Pre-grated cheese will almost always include cornstarch as an anti-clumping agent, and you can clearly taste it in the final product as a “flour-y” or “babypowder” overtone. As for Kraft shelf-stable “parmesan” cheese, the less said the better.
