In this tutorial, we learn how to make beef lo mein. Start off with thin sliced beef, then marinate with sugar, oyster sauce, and white wine. Marinade this for five minutes, then make the sauce. Use 1 c beef broth, 2 tbsp oyster sauce, 1 tbsp sugar, 1 tbsp sesame oil, and 2 tbsp soy sauce. Add in a small amount of corn starch to make this thicker, then set your wok on high with vegetable oil inside of it. Next, add in garlic with ginger and stir these until they are fragrant. Then, add in the meat and constantly move the meat with the spatula. After this is cooked, add in the vegetables that you would like and cook until the veggies are tender. Then, add in your sauce and let boil for a few seconds. Let this thicken, then add in your noodles. Stir this all together, then when well mixed, serve and eat!
