The Basque asador way, from Tolosa to Hondarribia: one thick, well-marbled bone-in rib of older beef, salted with nothing but coarse salt, cooked hard over glowing coals so the outside chars and the inside stays red and warm, sliced and served on a hot plate with green peppers.
1 bone-in rib steak (txuleta / côte de boeuf), 2 to 2 1/2 inches (5 to 6 cm) thick, about 2 1/2 to 3 lb (1.2 to 1.4 kg), from aged, well-marbled beef
2 tbsp coarse sea salt (gros sel)
For the peppers: 1 lb (450 g) small green peppers (Padrón or Gernika) or a jar of roasted piquillo peppers
2 tbsp good Spanish olive oil
Flaky salt
How to make it
Take the steak out of the fridge 1 hour before cooking so it is cool, not cold, at the center. Do not salt it yet: the asadors salt at the grill.
Light a full chimney of hardwood lump charcoal (or oak). When it is covered in white ash, spread it in a single, even, thick layer and set the grill 3 to 4 inches above. You want it hot enough that you can hold your hand there for only 2 seconds.
Rub the steak with nothing. Scatter half the coarse salt over the top side, lay it salted side down on the grill, then salt the side now facing up.
Cook 6 to 8 minutes without moving it, until the underside is charred dark brown in places and the fat is crackling. Turn it once and cook 6 to 8 minutes more. Stand it on its fat edge for 2 minutes to render the cap.
Check the center with a thermometer: 115 to 120°F (46 to 49°C). The Basque way is red and warm inside, never cold and never pink-grey.
Rest 5 minutes on a board, then knock the excess coarse salt off.
While it rests, toss the green peppers in olive oil and blister them on the grill 3 to 4 minutes, turning, until soft and spotted; salt them well. (Or warm the piquillos in a pan with the oil.)
Cut the meat off the bone in one piece, slice it 1/2 inch thick across the grain, and lay the slices back around the bone on a very hot plate (a cast-iron pan heated on the grill works) so each person can sear their slices a little more if they like. Finish with flaky salt and the peppers alongside.
Tips
Indoors: a smoking-hot cast-iron pan for 5 minutes a side, then 250°F (120°C) oven until 115°F inside.
Older, fattier beef is the point; ask the butcher for a rib from a mature animal, aged at least 30 days.
