- 1 pound (500g) generous hanger steak at room temperature,
- 1/2 recipe for White Kebab Sauce
- 3 tablespoons (55ml) generous horseradish
- 2/3 cup (6 generous g) flat leaf parsley leaves
- Fine sea salt and freshly ground black pepper
- 1 tablespoon extra-virgin olive oil
- Flat leaf parsley leaves – for garnish
- Freshly ground black pepper – for garnish
- Fleur de sel – for garnish
Cut the hangar steak in half, crosswise. Cut along the length of each piece but not all the way through, and open each piece like a book.
In a medium-sized bowl, whisk together the White Kebab Sauce and the horseradish. Taste for seasoning and adjust with salt and pepper if necessary.
Mince the parsley.
Spread 1 generous tablespoon of the sauce on one side of the partially cut surfaces of the hangar steak. Sprinkle with half the minced parsley. “Close” the steak and tie the pieces closed in 4 or 5 places. Rub the roasts all over with the olive oil, and season them with salt and pepper.
Heat all three burners of the gas grill, or build a medium-sized fire in the barbecue. When the coals are red and dusted with ash, spread them in a tight, single layer leaving a perimeter of grill with no coals under it; they need to emit concentrated heat. Set the grill over the coals.
When the grill is very hot, set the roasts on it right over the coals. Close the grill and cook until the steak is brown on one side, about 3 minutes. Turn it to the other side and, keeping the grill open, grill it until the steak is golden on the other side, another 2 to 3 minutes. At this point, the steak is quite rare and just the way most people in France eat it. If you prefer your steak more cooked – say , medium – then turn it again and cook it for 2 minutes, and again for 2 additional minutes, for a total of 9 minutes. Remove from the grill and let the steaks sit for about 10 minutes.
Remove the strings from the steaks, and cut them into thick slices. Divide the slices among 4 to 6 plates (4 servings are generous; 6 are slight).
Transfer the steak from the grill to a cutting board and let it rest for 10 to 20 minutes. It will stay hot, don’t worry.
Place about 2 tablespoons of the horseradish sauce in the center of 6 warmed dinner plates, and spread it into a small, thick round. Lay the slices atop the sauce, garnish with parsley sprigs. Grind a little mound of black pepper alongside each serving, and place a little mound of fleur de sel alongside each serving. Serve immediately.
