Florence, Tuscany — the bistecca fiorentina is associated with the feast of San Lorenzo (August 10), when the Medici family reportedly distributed beef to the population. The Chianina cattle breed, from the Chiana valley between Florence and Siena, has been bred for quality beef since the Roman period.
Bistecca fiorentina is not simply a grilled steak — it is a specific steak (the T-bone from the Chianina or other white Tuscan breeds), a specific thickness (4-5cm minimum — at least 1.2kg), and a specific technique: grilled over a very hot wood or charcoal fire to a crust on each side while remaining completely rare in the centre (al sangue — to blood). It is never cooked beyond rare; any more doneness is considered a violation of the preparation. It is seasoned only with salt (after cooking, not before — salt draws moisture that prevents searing) and drizzled with raw Tuscan extra-virgin olive oil after slicing. The preparation has protected status and is a matter of regional pride.
Bistecca fiorentina at 45-50°C internal temperature is rare and warm at the centre — the crust is charred and savoury from the wood smoke and the Maillard reaction; the interior is red and yielding, with the particular sweetness of Chianina beef. The olive oil at the end adds a green, slightly bitter note that completes the flavour. It is the greatest single expression of Tuscan cooking.
The steak must be from Chianina (the great white Tuscan cattle breed), or Maremmana — the breed's characteristic flavour and fat distribution are part of the dish. Minimum thickness: 4-5cm. Minimum weight per steak: 1.2kg. Bring to room temperature for 2 hours before cooking. Grill over burning charcoal or wood — the fire must be fierce, not gentle. No oil before grilling — the fat on the steak is sufficient. 4-5 minutes per side without moving, then briefly sear the T-bone edge. Internal temperature: 45-50°C (115-120°F) — completely rare. Rest 5 minutes standing on the bone. Season with coarse salt immediately after removing from the grill. Drizzle with raw olive oil. Serve the whole steak, sliced at the table.
The resting position matters — rest standing on the T-bone (balancing the steak upright on the bone edge) rather than lying flat, so juices distribute evenly and don't pool on the cutting board. The Tuscan olive oil at the end is the only condiment — never lemon, never sauce, never butter. The bone is the most prized portion — the marrow, exposed by the cut, should be eaten with a small spoon.
Cooking beyond rare — the bistecca is non-negotiably rare; medium or well-done is an error. Salting before cooking — draws moisture that prevents the crust. Grilling at insufficient heat — the crust must form within 4-5 minutes; too-low heat means the interior overcooks before the crust forms. Using non-Chianina beef — the breed's specific fat profile and flavour are the point.
