I don’t suppose that technically there’s an absolute, written in stone recipe for Saltimbocca. After all, the word means “jump in the mouth” in Italian, and you could probably name a number of ingredients that you might like to have saltim your bocca.
But generally, in Italian restaurants, saltimbocca usually refers to a specific preparation, though even that is open to variations. I’ve had veal saltimbocca and I’ve had chicken saltimbocca. But until I visited Tre Bambine, a new restaurant in the former Spice Modern/Lake Eola Yacht Club space, I had never had meatloaf saltimbocca.
Mind you, it was veal meatloaf, but still. This culinary interpretation was completely lost in the translation.
