Beef selection is best to use beef brisket parts, soak in water for 4 hours, change the water every 2 hours.
Cut the beef into strips and add the coriander leaves, cinnamon, star anise, thirteen spices, ginger, shallots, soy sauce, onion,
Salt to the right amount, marinate for 12 hours, and then mix and pinch several times in the middle to marinate evenly.
Put the marinated beef in a cool place to dry, and in rainy weather, use an electric fan to dry.
I change the dried beef strips to a small thin strip. Air fryer preheat to about 180 degrees, bake for about 15-20 minutes, burnt, tender, crispy, and fragrant, gravy are tested out, turn over a few times in the middle, just fine. Guaranteed to do this out of the beef you won't eat enough!
