Ingredients:
1 lb beef (flank, chuck or any tough cut)
1 teaspoon baking soda
1 tablespoon soy sauce
1 tablespoon rice wine (or dry sherry)
1 tablespoon cornstarch
1 teaspoon sugar
2 tablespoons water
1 tablespoon vegetable oil
Instructions:
Prepare the Beef:
Cut the meat into small pieces thinly against the grain.
Put some baking soda in a bowl and mix it with the beef slices until they coat completely. Leave them to sit for 15-20 minutes. This helps to break down the fibers and tenderize the meat.
Rinse and Marinate:
After sitting with baking soda, rinse well under cold water to remove any remaining baking soda.
Use paper towels to dry up all moisture on beef strips.
Combine soy sauce, rice wine, cornstarch, sugar and water in a bowl. Stir until sugar and cornstarch dissolves in well mixture.
Beef slices should be added onto marinade ensuring they are all coated well.
Marinate for at least 30 minutes but for best results cover and refrigerate for up to 2 hours.
How to cook the beef
Heat up some vegetable oil in a wok or a big frying pan over high heat.
Once it is hot, add the slices of beef that have been marinated, making sure they are arranged in a single layer.Do not crowd the pan, if you have to do it in batches, do it that way.
Stir-fry for 2-3 minutes until it is browned and cooked through.
Remove meat from the frying pan and set it aside. Repeat with any remaining beef.
