Orange Beef NYT
For the sauce:
For the beef:
Make the sauce: Heat oil in a small sauce pan set over medium-high heat. When it begins to shimmer, add ginger, jalapeño and orange zest and stir to combine. Sauté mixture until ingredients soften, approximately 2 to 3 minutes, then add garlic and continue cooking until it softens, approximately 1 to 2 minutes longer.
Add orange juice, brown sugar, rice vinegar, soy sauce and fish sauce to pan and stir to combine. Allow mixture to come to a boil, then lower the heat and cook, stirring occasionally, until it thickens and reduces by half, approximately 10 to 15 minutes.
Meanwhile, prepare the meat: Combine egg white, cornstarch and salt in a bowl. Add steak, tossing to coat the meat with the batter.
In a large skillet or wok set over high heat, heat oil until it shimmers and is about to smoke. Add beef to the pan or wok in a single layer and cook without stirring until the bottoms of the pieces are crisp and golden, approximately 60 to 90 seconds. Add white pieces of scallion and chiles to the pan, then turn the beef pieces over and cook the other sides, stirring occasionally, about 3 minutes more for medium-rare. Transfer to a platter.
Pour orange sauce into the hot pan or wok, let it boil and stir it as it thickens. Add meat and white scallions and stir to coat with the sauce. Return meat and sauce to the platter and scatter green scallions over the top. Serve with steamed broccoli and white rice.
