'Cat socks' are traditional cucina povera dish from Modena that is known throughout Emilia-Romagna. It goes by many names: papparocci, paparuccia, cassagai, ciribusla, mariconda or bagia, and it can be a snack, a starter or even a main course.
Basically it's a mix of borlotti (or canellini) beans and polenta, left to cool and then sliced into little squares and fried. Usually served with tomato sauce. We like this recipe from the Taste for Bologna blog.
