Prepare the king oyster mushrooms by removing the caps and using only the stems.

Remove excess moisture from the ground beef and pork using paper towels.

Mix the ground beef and pork with minced garlic, soy sauce, black pepper, sesame oil, and rice wine in a bowl.

Shape the meat mixture into small round patties and flatten them gently.

Place a piece of king oyster mushroom stem on each patty and wrap the meat mixture around it.

Heat a pan with a small amount of oil and cook the patties over medium heat until they sizzle.

Reduce the heat to low, cover the pan, and let the patties cook through.
