Florence, Tuscany
Florence's beloved tripe preparation: honeycomb tripe slow-braised in a dense tomato sauce with onion, celery, carrot, and fresh basil until the tripe is completely tender and the sauce has reduced to a thick, glossy coating. Finished with Parmigiano Reggiano grated generously over at the table. Sold from the traditional 'lampredottai' street carts of Florence alongside the lampredotto (abomasum) sandwich — Florentine tripe culture is the most vibrant in Italy. Eaten standing at the lampredottaio's counter with a glass of Chianti.
Rich, tomato-glazed tripe with the herbal freshness of basil and a generous blizzard of Parmigiano — street food of Florentine civic identity
Tripe must be pre-blanched in boiling water (discard the water) to remove residual odour before the main cooking. The tomato base must be long-cooked and dense before the tripe is added — watery tomato produces a thin sauce. The basil (added in the last 10 minutes, not at the beginning) provides a herbal freshness that cuts through the tripe's richness. Parmigiano is added tableside, not during cooking — it would make the sauce grainy.
Florence uses honeycomb tripe (trippa) for this dish — smooth tripe (folio) is for lampredotto only. The canonical serving: a bowl of trippa alla fiorentina, Parmigiano, a piece of crusty bread, and a quarter-litre glass of house Chianti at the counter of a tripperia. For home cooking: add a small piece of Parmigiano rind during braising for additional depth.
Not blanching the tripe first — produces off-odours in the final dish. Thin tomato sauce — the sauce must be dense enough to coat the tripe completely. Adding basil too early — it becomes bitter and unpleasant with extended cooking. Under-cooking the tripe — it must be soft enough to cut with a spoon.
