Flat Iron steak is a tender, flavorful cut of beef that's perfect for grilling and serving with a simple sauce like this Asian-style version made with hoisin, sherry and orange marmalade.
Preheat a gas or charcoal grill to medium-high heat (450 to 475°F). Remove the steak from the refrigerator 30 minutes prior to cooking to allow it to come to room temperature.
To prepare the sauce, heat the vegetable oil in a small saucepan over medium heat. Add the garlic and ginger and sauté for 1-1/2 to 2 minutes, stirring constantly. Do not brown.
Stir in the sherry and orange juice, bring the mixture to a rapid simmer and cook for 1 minute. Stir in the hoisin sauce and orange marmalade and reduce the heat to medium-low. Continue cooking for 5 to 7 minutes, stirring often.
Remove the sauce from the heat and transfer about 2 tablespoons to a small bowl. Add the butter to the remainder, stir until melted and cover to keep warm.
Brush the steak on both sides with a bit of sesame oil and season with salt and pepper. Oil the grill grates, add the steak and grill for 2 minutes on the first side.
Turn the steak over and brush the reserved sauce on top. Grill for 2 to 3 minutes on the second side (for medium rare), then transfer to a cutting board and allow to rest for 7 to 8 minutes.
To serve, cut the steak into thin slices against the grain and drizzle with the Orange-Hoisin sauce. Pass additional sauce at the table.
