Another incredible horse meat delicacy in Italy is the "pesto di cavallo" from Parma: imagine a tartare, but without all the yolk and capers bullshit and made of horse rather than beef…
And in Italy is strictly forbidden to slaughter work-horses for human consumption, though sometimes they crack down on an illegal butchery in Sicily, in the north you should be fairly safe.
Parma is an incredible town for food, and the whole Emilia-Romagna region is worth an extended visit. I spent 2 weeks exploring the area last summer and loved it.
Within a 30 mile radius of Parma, you can sample some of the best fruits and vegetables, stuffed pastas (ravioli), Parmesan cheese, balsamic vinegar, wine, and sausages in the world -- almost unbelievably cheaply! If you're looking for pesto di cavallo in particular, there's a great sandwich shop in Parma called Pepèn that I'd suggest.
