In a food processor, combine the ginger, garlic, chili peppers, scallions, and shallot and pulse until minced. Add half the minced aromatics to a large bowl (reserve the remaining half of aromatics for the sauce).
To the bowl of aromatics, add the pork, egg, sesame oil, and soy sauce and use your hands to mix all the ingredients together. Note: At this point, you can fry up a dime-sized piece of the mixture to taste for flavor. Adjust the salt and pepper as necessary.
Pour the panko over the mixture and gently work it in with your hands. Do not over-mix the meat.
Roll the mixture into balls, about 1” in diameter and transfer to a plate.
