Combine the salt, sugar, rose liquor, light soy sauce and garlic in a large shallow dish and stir to dissolve the sugar
Place the pork belly strips into the marinade and massage well all over. Set aside for 20 minutes. The pork will produce a little liquid
Massage the pork again in the now wetter marinade until the lean meat in the pork belly feels smooth and silky to the touch. Leave to marinade for a further 1.5 hours
After this time, heat the vegetable oil in a wok and add the pork belly strips in one layer (so they are not overlapping.) Pour over the marinade, bring to the boil and cover. Cook for 2–3 minutes, all the while swirling your wok over the heat to prevent the pork from sticking and burning
Turn the heat down to medium and turn the pork over. Continue this process until the sugar caramelises and the pork takes on colour. This should take about 20–25 minutes. Remove from the wok, sprinkle over sesame oil, slice diagonally and serve
