Empty the oil from the wok and put the pork aside for the moment. Take the green onion and the block of ginger as a whole – no additional oil required this time! Just don’t wipe or wash your wok in between the steps; it will stay just oily enough for this to work. Sauté the onions and the ginger lightly, and then add the pork back into the mix, frying them together. After a minute or so, pour the soy sauce on them, and don’t be alarmed if it catches fire at first; this explosive element is essential for the ingredients to be able to absorb all the additives properly. You can shake the wok around – that’s why thin-and-light is important, so this is easy to do – to make sure the distribution is even, and then add Zhenjiang vinegar 1, the salt and brown sugar in that order. This will create a sticky sauce that should attach itself to the pork evenly, so stir the dish at this time to facilitate that process.
