Another dish from Emilia Romagna, featuring a stuffing of spinach, ricotta and Parmesan, substituting pasta with pancakes. This dish is also found in Florence, under the title of Crespelle alla Fiorentina (I thought a display of my arcane intimacy with regional Italian cooking and dialects was in order). Frozen leaf spinach drained very well is good for this dish. You will also need a non-stick Swiss roll tray.
