with vinegar. that tenderizes and cleans it. then it's cooked with tomato and mint. in rome this is really the only way you find tripe. go to another place, florence included, and the tripe is prepared differently. >> stewed stomach may not sound appealing, i know, but believe me, these are really tasty flavors. the roman poor didn't have much to work with, but against the odds they wound up making some of the very best food in the city. what can i say? thanks a lot. thank you so much, kate.
