Bring a cooking pot and fill it with water. Once the water starts boiling, you must add the chicken to it. The chicken will get soft in this boiling water.
This will take almost an hour to get in shape. Take the chicken out of the boiling water and also preserve some of the chicken water for later.
Now take off the skin from the chicken and then shred the cooked chicken either using your hands or a fork if cool enough to handle.
Now you must make a mixture in a mixing bowl or container.
Add flour into it and then pour some milk. You should also add butter. It is better to melt the butter before using it.
Stir all of them to a creamy consistency. Transfer this blend to the cooking chicken liquid. Also, add the shredded chicken back to it. Simmer more.
Sprinkle some salt and pepper over it.
Add some crackers at the top for the final touch and then serve.
