In a mixing cup, combine the 100% fruit juice, broth, soy sauce, mirin, garlic, and ginger. Add about 8 grinds of black pepper.
Pour the Teriyaki Sauce into a 1-gallon resealable plastic freezer bag and add the oil. Add the desired beef, seal, and marinate at room temperature for 30 minutes.
For a stir-fry sauce, do not use the oil, but mix in the cornstarch.
Add to the wok at the end, cooking just until the sauce thickens to coat the other ingredients, 60-90 seconds.
