For a vegetarian option, substitute beef broth with vegetable broth and omit oyster sauce or use a vegetarian mushroom-based oyster sauce. Adjust sugar to taste. This sauce is excellent with beef, chicken, pork, tofu, or mixed vegetables. For a thicker sauce, add a tiny bit more cornstarch slurry. Store leftovers in an airtight container in the refrigerator for up to 5 days.
