6 to 8clovesblack garlic, peeled and roughly chopped
Trim any excess fat from the steaks, slice them into thin strips for stir-frying, and place in a bowl.
Add the soy sauce, 1 tablespoon of the sesame oil, and some freshly ground black pepper.
Stir to coat the meat thoroughly and set aside at room temperature for 15 minutes.
Heat the remaining tablespoon of sesame oil in a wok or heavy skillet over high heat. Add the beef along with the juices that have accumulated, and stir fry for 30 seconds.
Reduce the heat to medium-high, add the black garlic, and continue stir-frying until the garlic breaks down slightly and combines with the meat juices to form a sauce that coats the beef, 1-1/2 minutes.
Stir in the scallions and remove from the heat. Serve immediately.
