Sesame Stir Fried Beef, Onions & Ginger (Mark Bittman) - cooking recipe

Ingredients

1/4 cup soy sauce
2 tablespoons rice vinegar
2 teaspoons sugar
12 -16 ounces flank steaks (or other tender beef cut) or 12 -16 ounces sirloin steaks (or other tender beef cut)
salt & freshly ground black pepper
2 tablespoons dark sesame oil
3 medium onions, thinly sliced
1 tablespoon garlic, minced
4 teaspoons fresh ginger, minced
chopped scallion (for garnish)
2 tablespoons toasted sesame seeds (for garnish)

Preparation

Slice the beef as thinly as possible, across the grain. (It's easier if you freeze it for 15-30 minute first.) Cut the slices into bite sized pieces. Sprinkle with salt and pepper.
Marinate the beef in 1/4 cup soy sauce, 2 T. rice vinegar and 2 teaspoons sugar.
Heat a large skillet over high heat until it smokes, 3-4 minutes. Add 1 T oil and the onions. Stir immediately, then stir every 30 seconds or so until the onions soften and begin to char slightly, 4-5 minutes.
Sprinkle the onions with salt and pepper and remove them; keep the heat high.
Add remaining oil to the pan, then the garlic and 1 T. of the ginger; stir and immediately add the beef. Stir immediately, then stir every 20 seconds or so until it loses its color, just a minute or 2 longer; stir in the onions.
Add the remaining teaspoon of ginger; cook until liquid is evaporated.
Garnish with chopped scallions and toasted sesame seeds and serve immediately over rice.
