Stir-Fried Beef with Tangerines, Green Beans, and Chiles
Slicing the beef paper-thin when stir-frying will get the meat nice and crispy, so make sure your knife is sharp. If tangerines are not in season, oranges make a fine substitute and no one will be the wiser. The only weird ingredient is the black Chinese vinegar. It has a sweet, malted flavor that is very traditional in Chinese cooking. If you’re a purist about Chinese food, the black vinegar will be worth the trip to an Asian market. If you can’t find it, I’m not going to tell anyone if you substitute balsamic vinegar.
