Beef and Broccoli Stir-Fry: 9/10. Overall, this was amazing stir fry. I added more to my sauce. Instead of the ground ginger, I used 2 teaspoons of garlic-ginger paste. I also added more of the soy sauce/brown sugar/cornstarch/water blend. I wanted more sauce to enjoy with my rice. The only thing I would do differently, is to marinade the beef in more than just the water, cornstarch, and garlic powder. I also added salt and pepper to my sauteed broccoli and onion; I also cooked it longer.
