Cut the beef across the grain into thin strips. Mix with 1 tablespoon dark soy sauce and a seasoning of pepper. Cover and set aside for 5-10 minutes.
Heat a dash of oil in a large wok or frying pan. Over a high heat stir-fry the beef in two or three batches, until just browned. Remove the beef as it browns. Do not overcook.
Reduce the heat, stir-fry the onion for a few minutes then add the celery and the garlic, mushrooms, snow peas and beef with the remaining soy sauce and black bean and garlic sauce. Stir or toss well until very hot.
Serve immediately with rice or noodles.
