Step 1

Cut the flank steak, against the grain, into bite size ⅛ to ¼ inch thick slices. If you have time, freeze the flank until semi frozen for easier cutting. Do let it thaw and drain any moisture before marinating.

Step 2

In a medium bowl, add everything for the marinating the beef (beef, water, cornstarch, oil, Shaoxing, salt, and baking soda). Mix the ingredients until everything is well combined and the beef is well coated with the marinade. Set aside to marinate for at least 10 to 15 minutes, or overnight in the fridge.*Do prepare the beef first so that it can marinade while you prepare the rest of the ingredients! This way you can maximize your time.*

Step 3

In a bowl, add all the ingredients for the sauce (soy sauce, water, sugar, cornstarch, and sesame oil). Mix until no more cornstarch clumps are visible. Set aside until needed.*If you prefer a thicker sauce, you can add an extra teaspoon or two of cornstarch. If you prefer a thinner sauce, reduce the cornstarch to 2 to 3 teaspoons.*

Step 4

While the beef is marinating, bring a medium pot of water to a boil. Add the broccoli florets and boil them for 30 seconds to 3 minutes, depending on your preferred tenderness. The cook time will also depend on how big the broccoli florets are. Once cooked, drain the broccoli and set aside.*We usually boil our broccoli for about 1 minute because we like it more on the crisp side.*

Step 5

In a wok or sauté pan, add enough oil to generously coat the bottom and heat over medium high heat. Once the oil is hot, add the marinated beef and cook until the beef is about 90 percent cooked. Make sure to separate the beef so that it gets evenly cooked. Cook in small batches if necessary. Remove from the wok/pan and set aside.

Step 6

Keep about 2 tablespoons of oil in the pan and turn the heat to medium. Remove excess oil if needed. Add the minced garlic and ginger and sauté until fragrant, about 15 to 30 seconds.

Step 7

Give the prepared stir fry sauce a good stir and add it to the garlic and ginger. Heat the sauce until it simmers. Once the sauce has thickened and looks glossy, add the beef and the broccoli. Stir and toss everything together until the beef and the broccoli are well coated in sauce.

Step 8

Transfer the beef and broccoli onto a serving plate and garnish with sesame seeds if you wish. Enjoy it while it's hot!
