How to cook fried chicken gizzards that are tender?
According to my grandmother, chicken gizzards should be parboiled before being breaded for frying. She suggests a 10- to 15-minute parboil (clean your gizzards, put them in a pot, fill the pot with cold water until the gizzards are just covered, and time the parboil from the moment you achieve a hard boil). She also suggests thoroughly cooling and drying the gizzards before breading them.
