2. Cut the washed chicken gizzards in half with a knife and open them by hand. You will find a lot of undigested food in the chicken gizzards, and you may even find pebbles and other sundries. This is normal. Just rinse it with running water.
After washing the inside of the chicken gizzard, you will find a thick yellow film on the inner wall of the chicken gizzard. Tear it off by hand, be sure to tear it off completely, because this thick yellow film is bitter.
After the yellow thick film is torn clean, simply rinse it with running water, and the inside and outside of the chicken gizzard will be completely clean.
