Classic Matambre Recipes

Steps:

• Combine the soy sauce, fish sauce, sesame oil, brown sugar, red pepper flakes, garlic, scallions and ginger in a large resealable plastic bag. Add the flank steak, seal the bag and massage the marinade into the steak. Marinate in the refrigerator for 2 to 4 hours.
• Preheat the oven to 375 degrees F.
• Bring a pot of water to a boil over high heat. Add the eggs and boil for 6 minutes. Remove to an ice bath to cool, then peel the eggs. Thinly slice the mushrooms. Mix together the mushrooms, kimchi, panko and scallions in a bowl and set aside.
• Remove the steak from the marinade (reserve the marinade) and pat dry. Spread the filling over the steak, leaving a 1 inch border around the edge. Lay the eggs end to end at the edge of the filling closest to you. Pick up the end of the steak with the eggs and roll up to the other side, enclosing the eggs and filling.
• Lay half the bacon strips next to one another on a work surface so they overlap slightly. Make a second row with the remaining bacon strips, overlapping the ends to make an extra-long rectangle. Place the steak, seam-side down, perpendicular on one edge of the bacon strips and roll the steak with the bacon. Tie a piece of butcher's twine around each strip of bacon to secure it to the steak, then tie a piece lengthwise around the roll. (This can be done a day ahead, covered and refrigerated.)
• Heat a large ovenproof saute pan or skillet over medium-high heat. Sear the rolled steak on all sides until golden brown, about 8 minutes total. Brush with the reserved marinade and roast in the oven until an instant-read thermometer inserted into the center registers 135 degrees F, about 35 minutes, brushing again with the marinade halfway through. Transfer to a cutting board and let rest for 10 minutes.
• Slice the steak and serve.

Steps:

• Butterfly the steaks by slicing them horizontally from 1 long side to within 1/2-inch of the opposite side. Pound the steaks between plastic wrap to flatten them further. Trim off all the sinew and fat.
• Lay 1 steak cut side up on a jelly-roll pan. Sprinkle the steaks with the vinegar, garlic, and thyme. Cover and marinate, refrigerated, for 3 hours.
• Preheat oven to 375 degrees F.
• Lay the steaks end to end, in the direction of the grain of the meat, so that they overlap. Pound the overlapping area to join them securely. Spread the spinach leaves evenly over the meat and arrange the carrots across the grain of the meat in parallel rows about 3 inches apart. Place the eggs between the carrots. Scatter the onion rings over the meat, sprinkle with parsley, salt, and pepper.
• Carefully roll the matambre with the grain, jelly roll style, into a thick long cylinder. Tie with butcher's twine at 1-inch intervals. Place the matambre in a large casserole or roasting pan along with the beef stock. Add enough cold water to come a third of the way up the roll. Cover tightly and bake 1 hour.
• Serve warm or chilled, sliced into 2-inch thick slices.
