Ingredients:

- 1 Tbsp (15ml) Light Soy Sauce
- 1 Tbsp (15ml) Dry Sherry or Shaoxing Cooking Wine
- 1 tsp (5ml) Sesame Oil (for marinade)
- 1 tsp (5g) Baking Soda
- 2 Tbsp (18g) Cornstarch (for beef coating)
- 4 cups (450g) Fresh Broccoli Florets
- 1 tsp Vegetable Oil (for broccoli)
- Pinch of Salt (for blanching)
- 1 cup (240ml) Beef or Chicken Broth (low sodium)
- 3 Tbsp (45ml) Light Soy Sauce (for sauce)
- 1 Tbsp (15ml) Dark Soy Sauce
- 1 Tbsp (15g) Brown Sugar (packed)
- 1 tsp Sesame Oil (for sauce)
- 1 tsp Freshly Grated Ginger (for sauce)
- 2 cloves Garlic, minced (for sauce)
- 1 Tbsp Cornstarch mixed with 2 Tbsp Cold Water (Slurry)
- 2 Tbsp Vegetable or Canola Oil (for cooking)
- 1 Tbsp Fresh Garlic, minced (for aromatics)
- 1 Tbsp Fresh Ginger, minced (for aromatics)
Instructions:
- Slice the flank steak thinly against the grain into strips about 1/8-inch thick.
- Marinate: In a bowl, combine beef strips with Light Soy Sauce, Sherry, Sesame Oil, Baking Soda, and Cornstarch. Mix well until the coating is fully incorporated. Set aside for at least 20 minutes.
- Mix Sauce: Whisk together Beef Broth, Light Soy Sauce, Dark Soy Sauce, Brown Sugar, Sesame Oil, grated Ginger, and minced Garlic in a separate bowl. Keep the cornstarch slurry aside.
- Blanch Broccoli: Briefly blanch the broccoli florets in boiling salted water for 1-2 minutes until bright green and tender-crisp. Immediately plunge into ice water to stop cooking; drain well.
- Cook Beef: Heat 1 Tbsp of cooking oil in a large wok over high heat. Add the marinated beef in a single layer (cook in batches if necessary). Sear quickly until browned, about 1 minute per side. Remove beef immediately and set aside.
- Sauté Aromatics: Add the remaining 1 Tbsp of oil to the wok. Add the fresh minced garlic and ginger. Stir-fry rapidly for 30 seconds until fragrant.
- Deglaze & Simmer: Pour in the prepared Stir-Fry Sauce mixture. Bring to a gentle simmer, scraping up any browned bits from the bottom of the wok.
- Thicken Sauce: Whisk the cornstarch slurry one last time and pour it slowly into the simmering sauce while stirring continuously until the sauce thickens and becomes glossy.
- Combine: Return the cooked beef and the blanched broccoli to the wok. Toss everything quickly to coat evenly in the sauce, ensuring the beef finishes cooking (about 1 minute).
- Serve Immediately piping hot over steamed rice.
