Ingredients:
- 1 lb Flank Steak or Sirloin (thinly sliced against the grain)
- 1 Tbsp Low Sodium Soy Sauce (for marinade)
- 1 Tbsp Shaoxing Rice Wine (or Dry Sherry, for marinade)
- 1 ½ Tbsp Cornstarch (Corn Flour, for marinade)
- ½ tsp Baking Soda (Bicarbonate of Soda, for marinade)
- 1 Tbsp Neutral Oil (e.g., Vegetable or Canola, for marinade)
- 5 lb Broccoli Crowns (cut into bite-sized florets)
- Pinch Salt (for blanching water)
- ½ cup Low Sodium Chicken Stock
- 3 Tbsp Low Sodium Soy Sauce (for sauce)
- 2 Tbsp Oyster Sauce (or vegetarian mushroom sauce)
- 1 tsp Dark Soy Sauce (optional, for color)
- 1 tsp Granulated Sugar
- 1 tsp Toasted Sesame Oil
- 1 Tbsp Cornstarch (for slurry, mixed with 2 Tbsp cold water)
- 3 Tbsp Neutral Oil (High Smoke Point, divided, for stir-fry)
- 1 Tbsp Fresh Ginger (finely minced)
- 3 cloves Garlic (finely minced)
Instructions:
- Slice the Beef: Slice the flank steak thinly against the grain. Aim for strips about 1/8 inch thick.
- Marinate (Velvet): In a mixing bowl, combine the sliced beef with the velveting ingredients (Soy Sauce, Rice Wine, Cornstarch, Baking Soda, and 1 Tbsp Oil). Mix thoroughly until the beef is fully coated and slightly tacky.
- Chill: Cover and refrigerate the beef for a minimum of 30 minutes. This allows the velveting agent to work its magic.
- Prep Broccoli: Bring a small saucepan of salted water to a rolling boil. Add the broccoli florets and blanch for 2–3 minutes until bright green and crisp-tender. Immediately drain and rinse with cold water (or plunge into an ice bath) to stop the cooking process. Set aside.
- Prepare Sauce and Slurry: In a small bowl, whisk together all the Sauce ingredients (excluding the Cornstarch Slurry and Sesame Oil). In a separate small dish, prepare the Cornstarch Slurry (1 Tbsp Cornstarch mixed with 2 Tbsp cold water).
- Heat the Wok: Place the wok over high heat until it just begins to smoke. Add 1 tablespoon of neutral oil.
- Cook the Beef: Add the marinated beef to the wok in a single layer, ensuring not to overcrowd the pan. Cook for 60–90 seconds per side until browned but still slightly pink inside. Remove the beef immediately using a slotted spoon and set aside.
- Sauté Aromatics: Add the remaining 2 tablespoons of oil to the wok. Immediately add the minced ginger and garlic. Sauté for 30 seconds until fragrant—do not let the garlic burn!
- Deglaze and Add Sauce: Pour the prepared Sauce mixture into the wok. Bring to a simmer, scraping up any fond (brown bits) from the bottom of the pan.
- Thicken the Sauce: Whisk the cornstarch slurry briefly, then pour it slowly into the simmering sauce while stirring continuously. Cook for 30–60 seconds until the sauce thickens and becomes glossy.
- Combine and Finish: Return the cooked beef and the blanched broccoli to the wok. Toss gently but quickly until everything is coated in the glossy sauce and heated through (about 1 minute).
- Final Touch: Remove the wok from the heat and drizzle in the toasted sesame oil. Serve immediately.
