1000g pork bone, 2 tablespoons bean paste, appropriate amount of onion, 3 slices of ginger, 3 cloves of garlic, 10 slice of pepper, 2 slices of aniseed, 2 slices of dried pepper, 5 slices of fragrant leaves, appropriate amount of soy sauce, appropriate amount of salt and 1 slice of cinnamon.

Practice steps:

(1) After thawing, pig bones were soaked in cold water for 3 hours, during which water was changed for 3 times to remove blood.

(2) Put the pig bones in cold water, boil them, skim off the floating foam and rinse them clean.

(3) Put the blanched ribs into the pot again, and add a proper amount of boiling water to make the water less than the meat.

(4) Add all the ingredients and add soy sauce for color matching.

(5) Add two spoonfuls of bean paste, add appropriate amount of salt, boil over high fire, and simmer for 2 hours until the meat is soft and rotten.
