First we start with the marinade. Mix together ½ tsp. salt, ⅓ tsp. baking soda, 1 tsp. corn starch, ½ TB. Chinese cooking wine, ½ Tb. soy sauce, ½ tsp. dark soy sauce, and beef sliced really thin against the grain. I like to use a sirloin or round steak.
Marinade the beef for 15 mins.
For the sauce combine 1 Tb. soy sauce, ½ Tb. oyster sauce, 2 heaping Tb. garlic black bean paste, 2 tsp. corn starch, ¾ C beef stock, and 1 Tb. brown sugar.
While the beef in marinating, prepare the noodles as directed on the package.
When the water comes to a boil, start cooking the noodles.
While the noodles are cooking, Heat your wok until it is smoking hot. Add the vegetable oil into the wok and swirl around the wok, creating a nice non stick coating.
Dump the beef and the marinade into the wok and cook on high until the beef is 3/4 of the way cooked.
Add the sauce to the wok and cook for about 1 min. or until the sauce has slightly thickened.
Add the drained noodles into the wok and cook and coat the noodles for another min. or until the sauce has thickened to the thickness you like.
Serve immediately and enjoy!
