Instructions
Put the pork in the freezer for about 1 hour to allow it to partially freeze and firm up, then slice the pork against the grain into 3 millimeter (1/8 inch) thick slices.
Combine the sliced pork, onion and spring onion in a large bowl and set aside.
To make the spicy pork marinade, combine all the ingredients in a bowl and stir until the sugar has dissolved.
Pour the marinade over the pork and, using your hands (wear food preparation gloves if necessary), rub the marinade into the meat until it is well coated.
Cover with plastic wrap and leave to marinate in the fridge for at least 1 hour.
Heat 2 tablespoons vegetable oil in a large frying pan or wok over high heat.
Stir-fry the pork, in batches, for 3-4 minutes, until well browned and caramelized. Add a little more oil between batches if necessary.
Serve as is, topped with sliced spring onion, or enjoy wrapped in lettuce and perilla leaves, with steamed rice on the side for a more substantial meal.
