Mix the beef with 2 teaspoons oil, 1 teaspoon soy sauce, and 1 tablespoon cornstarch. Let marinate at room temperature for 30 minutes.
Combine the sesame oil, soy sauce, hoisin sauce, hot water, and white pepper into a small bowl; mix well and set aside. Spread the beef out on a plate, and sprinkle on 3 tablespoons of cornstarch. Toss to coat the beef lightly, shaking off any excess.
Heat your wok until just smoking, and spread a quarter cup of oil around the wok. Add the beef and let the beef sear in the oil on one side for 30 seconds. Flip and let sear for another 30 seconds, and transfer to a plate. Turn down the heat to medium low and remove/discard the excess oil (if there is too much) leaving about 2 tablespoons of oil in the wok.
Add the ginger and let it cook for 15 seconds until it is just caramelized. Turn up the heat to the highest setting, and add the white portions of the scallions. Quickly add 1 tablespoon of Shaoxing wine, while continuing to stir-fry to deglaze the wok.
Next, add the beef and the rest of the scallions. Stir fry everything together for about 30 seconds, and add the sauce you prepared earlier. Continue to stir-fry. Hopefully your wok is hot enough, and you can get a nice scorch on your scallions (we say this because not all stoves can get up to the same level of BTUs!). Continue to stir-fry until the liquid has evaporated, and all of the sauce is clinging to the beef and scallions (are you drooling yet?). Spread 1 tablespoon of shaoxing wine around the perimeter of the wok. It should be sizzling and evaporate immediately; toss the dish again until the wine is cooked off to generate more wok hay. Turn off the heat, plate and serve!
