Kosher salt and freshly ground black pepper, to taste
Directions
In a small saucepan, bring the red wine to a boil over high heat. Reduce the heat to a simmer and add the sugar, orange zest, nutmeg, cloves and cinnamon sticks. Cook until the alcohol has cooked off and the liquid has reduced to 1 cup, 15 minutes. Remove from the heat and let cool completely, then strain.
In a plastic bag, combine the steak with the cooled marinade and seal. Refrigerate for 24 hours.
The next day, remove the steak from the marinade and pat it dry with paper towels. In a medium skillet, heat the olive oil over medium-high heat. Season the steak liberally with salt and pepper on both sides and add to the pan. Cook, flipping once, until golden brown and an internal temperature of 125° has been reached, 4 to 5 minutes per side. Transfer to a cutting board and let rest for 2 minutes, then slice, drizzle with olive oil and serve.
