Add the ground pork to a large mixing bowl. If it is tightly packed, use a fork or chopsticks to loosen it.
Add the minced ginger, chopped green onions, coconut aminos, Shaoxing wine, sesame oil (if using), and salt.
Mix everything together until well combined **
For the best flavor, cover and refrigerate for at least 30 minutes before using.
Notes
*Soy sauce is saltier than coconut aminos. If you are using soy sauce, adjust the additional salt level accordingly.
**Stirring in one direction helps develop the proteins and gives the filling its signature juicy, springy texture.
Taste before wrapping: Cook a small spoonful of the filling in a skillet first. This is the easiest way to check if it needs a little more salt before making an entire batch.
