What is Velveting?
"Velveting" is the secret technique used in many Chinese restaurants to create exceptionally tender, juicy beef. The marinade protects the meat during cooking and helps lock in moisture.

   • Soy sauce

   • Brown sugar
   • Oyster sauce
2. Set aside.

3. Drain immediately and transfer to ice water or rinse under cold water.
4. Set aside.

Step 4: Sear the Beef

1. Pat excess marinade from the beef with paper towels.
2. Heat 2 Tbsp vegetable oil in a wok or large skillet over high heat.
3. Add beef in a single layer.
4. Sear for about 2 minutes until lightly browned.
5. Remove beef and set aside.

Step 5: Stir-Fry the Aromatics

1. Add the remaining oil to the wok.
2. Add:
   • Green onions
   • Garlic
   • Ginger
3. Stir-fry for about 40 seconds until fragrant.

Step 6: Combine Everything

1. Return the beef to the wok.
2. Stir-fry for about 2 minutes.
3. Pour in the prepared sauce.
4. Stir continuously for 3–5 minutes until the sauce thickens and becomes glossy.
