one name, many sausages
In Calabria, a hard sausage made with black pepper and fennel, but no tomato.
In Puglia, a fresh pork, veal and mutton sausage with cheese and basil
In Lombardy, a fresh sausage flavoured with saffron and other spices; accompanies a risotto alla Milanese.
In Campania, dainty small pork sausages spiced with black pepper.
All, presumably, were made with brains (cervelli) once long ago, but no longer are. Little ones are cervellatina.
There's a Sagra della Salsiccia in honour of the Puglian cervellata, in late September in Toritto, near Bari.
