Pour out the hot oil and then heat the wok over medium low heat. Add back about 1 Tbsp of oil to the wok and let it heat up.
Once the oil is hot enough, add in your minced garlic and ginger, along with the white parts of the green onion that you cut earlier.
Let it cook for about 30 seconds to release all of the aromatics and then add your broad bean paste to the wok.
Stir-fry everything together in the wok for another 10-15 seconds and then add in your ground pork.
Spread the ground pork out on the wok and then add in your Shaoxing wine.
Now let the ground pork cook for about 1 minute on one side and then flip it over and let it cook on this side for another minute.
Once the ground pork starts to turn whitish in colour and is about 80% done, add in your eggplant to the wok.
Mix everything well together then add in your sauce.
Mix everything together then add in your water.
Turn the heat up to medium-high heat and stir-fry everything for about a minute and then add in your cornstarch slurry to the sauce by pushing the ground pork and eggplant to the side, exposing the sauce.
Mix the cornstarch and sauce well together which will thicken the sauce.
Now mix everything together for another 10 seconds or so and add in the green parts of the green onion from earlier.
Give it a few tosses and then drizzle in a little bit of sesame oil.
Turn the stove off and mix everything together for another 5-10 seconds and then remove everything from the wok and serve while hot.
