Makes 4 servings
2 tablespoons sugar
1 tablespoon kosher salt
1 tablespoon freshly ground black pepper
1 tablespoon hot red pepper flakes
1/4 cup porcini mushroom powder
1/4 cup extra-virgin olive oil, plus about 1 tablespoon
One 3- to 3 1/2-pound bone-in rib-eye steak, about 3 inches thick
3 cups trimmed arugula, washed and spun dry
Fine sea salt
Great extra-virgin olive oil for drizzling
Balsamic vinegar for drizzling
In a small bowl, combine the sugar, salt, black pepper, red pepper flakes, mushroom powder, garlic, and 1/4 cup olive oil and stir well to form a thick paste with the consistency of wet sand.
Rub the paste all over the steak, coating it evenly. Wrap tightly in plastic wrap and refrigerate for at least 12 hours, or overnight.
About 1 hour before grilling, remove the steak from the refrigerator and brush off the excess marinade with a paper towel. Place on a plate and let come to room temperature.
Preheat a gas grill or prepare a fire in a charcoal grill (use enough coals to keep the fire going for about 25 minutes).
Put the steak on the hottest part of the grill, cover, and cook, turning every 6 to 8 minutes, for about 25 minutes for medium-rare; the internal temperature should be 125°F.Transfer to a carving board and let rest for 15 minutes.
Meanwhile, dress the arugula with about 1 tablespoon olive oil and season with sea salt to taste.
Slice the meat against the grain into 1/2-inch-thick pieces. Arrange on plates or a platter, drizzle with olive oil and balsamic vinegar, and top with the arugula. Serve immediately.
