Florence, Tuscany
Florence's street obsession: the abomasum (fourth stomach of the cow) boiled for 90 minutes in a herbed broth until completely tender, then sliced thin and served inside a chewy bread roll (semmel) moistened by dipping the bread in the cooking broth, dressed with either salsa verde or a spicy peperoncino sauce (salsa piccante). Sold exclusively from the lampredottai (street carts), this is one of Italy's most uncompromising street foods — pungent, gelatinous, and utterly specific to Florence.
Gelatinous, intensely meaty abomasum, broth-soaked bread, and the sharp-herby cut of salsa verde — Florence's most confrontational and most beloved street food
The abomasum must be cleaned thoroughly of any remaining digestive material before boiling. The broth (with onion, celery, carrot, parsley, and black pepper) must be at a consistent simmer for 90 minutes minimum — the abomasum must be fall-apart tender, not chewy. The bread must be moistened by dipping the interior into the hot broth — 'bagnato' (wet) is the correct service. Salsa verde (the Florentine version: parsley, anchovies, capers, garlic, and white bread soaked in vinegar) is the canonical condiment.
For the double-wet service (bagnato doppio): both the inside of the bread and the sliced lampredotto are moistened in the broth before assembling — this is considered the correct technique by the serious lampredottai. The cooking broth, strained, is an exceptional base for a Fiorentina-style consommé. For the home preparation: use the same broth recipe as for bollito misto — the aromatics are identical.
Under-boiling the abomasum — it must be completely gelatinous, not at all chewy. Dry bread service (not dipping in broth) — the wet bread is what makes the lampredotto sandwich work. Using the wrong stomach — only the fourth stomach (abomaso) has the correct texture; the other three stomachs make different products. Too little or wrong condiment — the salsa verde or piccante is essential to cut the richness.
