Combine soy and sherry for marinade. Marinate steak pieces for 1 hour. Massage meat in marinade to aid tenderizing; drain, reserving marinade. Wash and soak mushrooms for 1 hour; drain, reserving soaking liquid, thinly slice. Wash, peel and roll cut carrots. (Roll cut means slicing on a slight bias in 1" lengths but turning the carrot a quarter turn (90 degrees) between slices. Wash cauliflower, trim off thick part of stems, and either break or cut florets into pieces about the size of the carrot pieces. Parboil carrots in boiling stock for about 3 minutes or until just begins to soften. Reserve carrots and stock.

Heat peanut oil in hot wok. When oil just begins to smoke, add drained steak cubes; stir briskly for 1 minute until meat begins to lose pinkness. Don't overcook meat or it will be tough. Remove to holding plate. Swirl remaining oil into wok. Add ginger, garlic and peppercorns; stir fry 15 seconds. Add cauliflower and mushrooms; stir fry 1 minute. Add specified amounts of liquids generated during preparation: reserved carrot stock, marinade, and mushroom soaking liquid; bring to boil. Cover wok; reduce heat to medium, and simmer 3 minutes. Remove lid; turn heat to high. When sauce boils again, add carrots and beef. Mix together. Splash vinegar down sides of wok. Push ingredients out of sauce, thicken with thin cornstarch paste. Sauce should be a light gravy. Add sesame oil. Toss in green onion. Serve.
