Why Use Baking Soda?
Baking soda raises the pH on the surface of the meat, preventing proteins from tightening too quickly during cooking. This technique, called “velveting,” is commonly used in Chinese restaurants.
Equipment Needed
- Sharp knife
- Cutting board
- Mixing bowls
- Measuring cups and spoons
- Large wok or skillet
- Wooden spoon or spatula
Step-by-Step Instructions
Step 1: Slice the Beef
Place the steak in the freezer for 15 minutes.
This firms the meat and makes it easier to slice thinly.
Slice:
- Against the grain
- About ⅛ inch thick
Thin slices cook quickly and stay tender.
Step 2: Marinate the Beef
In a bowl combine:
- Beef slices
- 2 tbsp soy sauce
- 1 tbsp cornstarch
- 1 tsp baking soda
- 1 tsp vegetable oil
Mix thoroughly.
Let marinate:
- Minimum: 20 minutes
- Best: 30 minutes
Step 3: Prepare the Sauce
Whisk together:
- ¼ cup soy sauce
- 2 tbsp oyster sauce
- 2 tbsp brown sugar
- 1 tbsp rice vinegar
- 1 tsp sesame oil
- ½ cup beef broth
For a thicker sauce:
- Add 1 tsp cornstarch
Set aside.
Step 4: Cook the Vegetables
Heat 1 tbsp oil in a wok over high heat.
Add:
- Bell peppers
- Onion
Cook:
- 3–4 minutes
- Stir frequently
Vegetables should remain slightly crisp.
Remove and set aside.
Step 5: Cook the Beef
Add remaining oil.
Spread beef into a single layer.
Cook:
- 1 minute undisturbed
- Stir and cook another 2 minutes
Add:
- Garlic
- Ginger
Cook 30 seconds.
Step 6: Combine Everything
Return vegetables to the pan.
Pour in sauce.
Stir continuously.
Cook:
- 1–2 minutes
Sauce should coat all ingredients evenly.
Step 7: Serve
