Preparation / Directions:
1.In bowl, dissolve cornstarch in sherry, oyster sauce, the water; add pepper flakes.
2.In wok, or large skillet, heat oil over medium-high heat; add ginger and garlic. Stir-fry 1 minutes. Add broccoli; stir-fry 3 minutes. Add red pepper, celery and green onions; stir-fry 3 minutes. Add cornstarch mixture and beef; stir-fry 3 minutes. Place on platter; if desired, garnish with green-onion flowers and serve with rice.
(note) The last time I made this, I doubled the sauce amount. I cooked the vegetables and removed them to a bowl; heated the meat in the wok and removed it to the bowl. I put only 1/4 cup of water in the doubled sauce. Placed the sauce in the wok and after it started to thicken, I added chicken broth until the sauce was the right consistency. Then add the vegetables and meat. Toss gently to coat with sauce.
