Leave the remaining peppercorns in the pan and add a tablespoon of avocado oil. Cook until sizzling, another 30 seconds to 1 minute. Using a spoon, scoop out the peppercorns and discard them, leaving the oil behind. Add the garlic and ginger and cook, stirring constantly until fragrant, about 1 minute. Add the pork, bean paste, wine, soy sauce, stock, coconut aminos, and glucomann powder. Bring to a boil and cook, stirring to break the pork up into small pieces until no pink remains, about 5-10 minutes.
