1 .750g chicken liver, soaked in clear water for 2-3 hours. Change the water 3-4 times in the middle, because the liver is a detoxification organ, which can dissolve the residual toxic substances in the water.

2. Take out the chicken liver, rinse it twice with clear water, put it in a pot, add 30 grams of vinegar, and boil it over high fire.

3. Turn to low heat, add aniseed, onion, ginger, sugar, yellow sauce and a small amount of soy sauce, and simmer for one hour. (always look at the pot in the middle to prevent the dry pot)

4. Add some large cloves of garlic, continue to heat 10 minute to collect juice, turn off the fire and adjust the salt, and pour it into a basin to cool.
