Cut the beef into thin slices 5 cm/2 inches long, cutting
across the grain.
Combine half the sesame oil, half the soy sauce,
the sherry, ginger and corn flour in a dish. Add
the meat and toss until well coated. Leave to
marinate for 15 minutes, then drain well.
Heat the oil in a preheated wok or heavy-based
frying pan and quickly brown the meat on all
sides for 2 minutes. Drain on kitchen paper.
Pour off all but 1 tablespoon of oil from the
pan. Return the pan to the heat, add the
chilies and stir-fry for 30 seconds.
Return the
meat to the pan and add the orange rind,
Szechwan pepper, sugar, the remaining soy sauce
and salt to taste.
Stir-fry for 4 minutes then
sprinkle with the remaining sesame oil. Serve
immediately, garnished with the orange slices
and parsley sprigs.
