Rehydrate Wood Ear Mushroom Firstly wash the them for 2 or 3 times and soak with warm water for 15 minutes or cold water for 1 hour.
Clean and trim the mushroomsAfter soaking, the wood ear mushrooms need to be re-washed carefully and remove the hard end part. Some bad quality wood ear mushroom may contain lots of sands, which will further spoil your dish.
Blanching the wood ear mushroom in hot waterAdd a small pinch of salt in hot boiling water and then cook wood ear mushroom for 1 minute. Transfer out and drain completely.
Thinly slice the pork. Add salt, cooking wine, white pepper and light soy sauce. Grasp (sometimes referred as messaging), the pork will get a sticky texture after 2 minutes grasping. Then add water (ginger and scallion water is the best), then continue mixing until the water is well absorbed. Add cornstarch to lock the liquid. Set aside for 10 to 15 minutes to let the flavors combined.
Add cold oil and mix well to separate each piece of pork slices. This can prevent the pork slices sticky to bottom of the wok.
Heat wok or pan firstly. Add cooking oil to form a 2-3 cm high layer (do not be scared by the oil amount, we do not eat them all). Spread the pork sliced in when the oil begins to warm but not hot. Let them stay for around 5-8 seconds and then quickly fry them until turns pale. Transfer out immediately.
Remove the extra oil (can be saved to make vegetable stir frying). Keep around 1 tablespoon of oil and fry garlic and pepper until aromatic. Place wood ear mushroom in. Add pinch of salt and light soy sauce to give them basic flavors. Mix well.
Return pork slices in. Quickly toss to mix well and serve hot! Don't over stir at this stage, the mushrooms and vegetables may scratch the starch layer off, which may cause the overcook of the pork slices.
