WHAT'S MONGOLIAN BEEF RECIPES

Steps:

• For the beef: Slice the flank steak across the grain into 3/4-inch (19 millimeters)-thick slices on an angle to make planks then cut the planks into 3/4-inch (19 millimeters) cubes. Combine the cornstarch, baking soda and salt with 2 tablespoons of water in a small bowl and set aside. Place the steak in a shallow bowl and add the water, vegetable, and cornstarch mixture. Massage all the ingredients into the meat. Cover and refrigerate for 2 to 12 hours.
• For the sauce: Combine the oyster sauce, hoisin sauce, soy sauce, cornstarch, vinegar, garlic and half the ginger in a small bowl and set aside.
• For the stir-fry: Heat the oil to medium-high in a wok or medium saute pan. Stir in the beef and cook to medium-rare, stirring constantly, about 3 minutes. Drain off excess oil. Add the garlic and remaining ginger and saute 20 to 30 seconds. Stir in the bell peppers and onions and let them cook until the edges of the onion and bell peppers begin to brown, about 2 minutes. Add the scallion whites, dried chilies and sauce, stir constantly and let it cook for about 2 minutes, until the sauce thickens.
• Transfer to a platter and garnish with the scallion greens.

Steps:

• Spread the flank steak out flat, cover with plastic wrap, and place in the freezer until partially frozen, 20 to 30 minutes.
• Remove beef from the freezer and slice across the grain into very thin slices.
• Whisk the chicken stock and cornstarch in a freezer-safe bowl until smooth; whisk in the hot chili oil, hoisin sauce, oyster sauce, sherry, sugar, soy sauce, and crushed red pepper flakes. Place the beef into the sauce, stir to coat well. Cover and freeze until frozen, about 1 hour.
• Remove from the freezer and allow to defrost, about 30 minutes.
• Heat a wok over high heat until very hot, and pour in the peanut oil. Immediately add garlic, cook and stir in the hot oil until fragrant, about 15 seconds. Mix in the Swiss chard and green onions; cook and stir the vegetables until they turn bright green, about 3 minutes, and then remove from the wok.
• Pour the defrosted beef mixture into the hot wok; cook and stir until the meat browns and the sauce forms a glaze, 3 to 5 minutes. Return the cooked vegetables to the wok, sprinkle with salt and pepper, mix to combine well; serve hot.
