Note from Ricardo
Speck is similar to prosciutto, as it is an Italian ham, but it is smoked. Prosciutto that we buy here is usually raw and salted, while in Italy there is a distinction between prosciutto crudo, raw, and prosciutto cotto, cooked. If you find it whole, have it cut into ½-cm (¼-inch) thick slices, then cut it into small pieces. Otherwise, look for a good Italian prosciutto. Guanciale is made from pork cheek, salted and dried. You can find it in Italian grocery stores.
