Cook’s Note

This cake is very rooted in Tuscan traditions. There is no yeast, so it won't rise at all. The flavor is very specific, not really kid-friendly, but it grows on you as you develop your Tuscan palate. This flat-cake is usually served with wine and not with coffee, as you truly need to wash this one down!
