Bistecca alla Fiorentina — Florentine T-Bone Steak

Ingredients

• 1.0–1.5 kg Chianina T-bone or porterhouse steak, Vitellone Bianco dell'Appennino Centrale IGP preferred; cut 5–6 cm thick (4–5 fingers); sourced from a specialist butcher
• 2 tsp coarse sea salt, applied immediately before cooking
• 1 tsp black pepper, freshly ground; applied immediately before cooking
• 2 lemon wedges, served alongside at table
• To serve
• 30 ml extra-virgin olive oil, Tuscan preferred; for the table, not for cooking
• 600 g roasting potatoes, roasted with rosemary alongside; served at table

Method

1. 1
   Remove the steak from refrigeration at least 2 hours before cooking and leave uncovered at room temperature. The meat must be completely ambient — cold at the centre will prevent the rare interior the dish requires. Press the flat of your palm to the thickest part: it must feel room temperature, not cool.
2. 2
   Build a live-ember fire using oak (leccio), olive wood, or vine branches. Allow the wood to burn down fully to white-ash embers before cooking begins. There must be no open flame beneath the grill. The embers are ready when they glow orange-red under a uniform white-grey ash surface and radiate intense, steady heat — hold your hand 10 cm above the grill rack for no more than 2 seconds.
3. 3
   Season the steak generously on both sides with coarse sea salt and black pepper immediately before it goes onto the grill. Apply no oil, no marinade, no acid. This is where the dish lives or dies: any oil or acid applied before cooking suppresses the Maillard crust that is the defining character of the bistecca; once seasoned, the steak must go directly onto the live embers without delay.
4. 4
   Lay the steak flat on the grill over the white-ash embers. Do not move it. Grill 5–7 minutes per side for a 1 kg steak. Turn once only, using tongs — never a fork. The crust is ready to turn when the underside releases cleanly from the grill bars and is deeply charred and almost black; pressing the surface with tongs meets firm resistance at the crust with give beneath.
5. 5
   After both flat sides are charred, stand the steak upright balanced on the T-bone for a final 5 minutes. This heats the meat close to the bone without overcooking the faces already grilled. The bone-side meat will shift from deep red to deep pink. The steak will hold its position on the bone without support.
6. 6
   Remove from the grill and rest on a wooden board for no more than 5 minutes. The exterior will remain very dark; the interior, when carved from the bone at the table, must be deep pink at the edge grading to bright red at the bone. Serve immediately with lemon wedges alongside — the lemon is applied by the diner, not the cook.
