In a bowl, mix together the sugar, garlic, and cornstarch, then add the ginger, soy sauce, and wine and mix again until well blended. Place the beef slices in a bowl and pour in half of the marinade, mix with the beef, cover and let marinate for 1 hour.

Heat half of the oil in a large non stick pan, a wok pan would be perfect, then add the broccoli and stir fry for 2 minutes then remove and set aside.

Heat the remaining oil in same pan. Drain the beef and add to the pan, stir fry for 3 minutes then add the oyster sauce and stir fry for 1 minute. Add the remaining marinade and the beef broth.

Cook while stir frying, that means stirring constantly, until the liquid evaporates and the mixture becomes thick, then add the broccoli and stir fry for 1 more minute to heat the broccoli through.

Serve with steamed rice on the side.
