Thaw the meat in advance! Adding cabbage or extra kimchi to stir-fry together tastes great! Try adding a small amount of curry powder, too.
Add olive oil to a preheated pan and sauté 1T minced garlic.
Add pork shoulder, 0.8T cooking wine, 1.5T allulose, 0.4T black pepper, and 0.6T oyster sauce, then stir-fry.
Pour 0.8T soy sauce along the edge of the pan and let it bubble as if slightly burning, then mix it with the meat (medium heat).
When the meat is about half cooked, add onion and green onion, then add 0.7T gochujang, 1T red pepper powder, and 2T water. Stir-fry. (If you want it drier, skip the water) (medium heat)
Finish by stir-frying on high heat for a short time at the end.
