Slice the round steak into strips of 6 mm
thick, then cut the strips into 5 cm lengths. Use a bowl to combine the
oil, sesame seed, garlic, soy sauce, sugar, chili and pepper. Pour the
mixture over the meat in a bowl and leave to marinate while preparing
the other ingredients.
Cut the mushrooms into half if they are
small, or slice them thickly if large. Wash and trim the scallions until
the part where the green leaves start to separate. Then cut the solid
part into 5 cm lengths. Use bamboo skewers to thread in an alternate
manner a piece of meat, onion and then mushrooms twice. Dip the skewers
in flour, and then in the beaten egg. Heat a frying pan with enough oil
to cover the base. Oil should be hot but not smoking. Cook the skewers
in the pan until crisp and brown. 2-3 minutes on each side. Serve hot
with steamed white rice.
