Step 1

Slice the beef against the grain. Mix with light soy sauce, rice wine, cornstarch, water and sugar. Coat with oil then leave to rest for 15 minutes.

Step 2

If using fresh ones: Gently separate the sa-ho fun by hand into long strands (try not to break them into small pieces).

Step 3

If using dried ones: follow the instructions on the package to cook then rinse under cold water prior to stir-frying.

Step 4

Pour oil into a hot wok. Stir in the marinated beef slices. Fry until they just turn pale (do not overcook). Dish out and leave the oil in the wok.

Step 5

Put in sa-ho fun. Gently stir around with a pair of chopsticks. When the sa-ho fun begins to wilt, add in beansprouts and onion. Fry for 30 seconds or so.

Step 6

Add the beef and Chinese chives. Pour in light soy sauce and dark soy sauce. Cook for a further 30 seconds.
