This was tasty and really good – I used a good quality flank steak and cut it very thin against the grain.
3 T. oyster sauce
2 T. soy sauce
1 T. marsala or sherry
3 T. water
4 t. sugar
1 T. cornstarch
1 lb. flank steak – cut into thin strips
1/3 c. green onions – sliced on the diagonal into 1/2″ slices
1 T. minced ginger
1 lb. broccoli florets
To make the sauce, add the oyster sauce, 1 T. soy sauce, the sherry or marsala, 1 T. water, 2 t. sugar and 1 t. cornstarch. Mix it well and set it aside.
Marinate the steak in 1 T. cornstarch, 2 T. water, 1 T. soy sauce, and 2 t. sugar in a Ziploc bag for about 15 minutes.
Heat some oil in a wok. Add the steak and stir fry it for about 2 minutes. Remove the steak from the wok and set aside.
Add a little bit more oil and stir fry the green onions and the ginger for about 30 seconds. Add the broccoli and 1/4 c. water. Cover and cook for about 3 minutes.
Return the steak to the wok and stir in the oyster sauce mixture. Cook until the meat is just barely done and the sauce has thickened a bit.
Serve over rice.
