Other classics on the table of the 25th or 1st are the cotechino or the zampone, a sort of boiled salami, the zampone encased in an empty pig's foot. Other classics side dishes include mashed potatoes and lentils. Other side dishes may be served and the antipasti will vary as well as the dessert but often includes at least one of the following: Panettone, Certosino (or Pan Speziel) or the Panone. The first two are rather labor intensive so many people buy these at a bakery. The Panone is often made at home and each family seems to have their own version of the recipe.
In Bologna, we usually eat magro on the 24th. Magro, which literally means "thin" and meant as "light meal"was supposed to be a light no-meat meal for Christmas eve. A typical primo would be tortelloni, this pasta is stuffed with ricotta as well as Parmigiano and either spinach, swiss chard or parsley and served in a butter and parsley sauce. And in case you think that this one dish is pretty light, you should consider that this is only the first course and does not include a number of antipasti, second course and side dishes... and naturally dessert.
I'm not sure that Bolognese ever took the "light"meaning very seriously as yes, they generally do not eat beef, pork or chicken on Christmas eve but they definitely do not hold back on the variety of seafood goodies they bring to their tables! That said, the 7 seafood dishes on Christmas eve is not a tradition in Emilia Romagna. So magro today only means no meat and it has nothing to do with being or getting thin. We think about thin come January!
