Water should be 3-3.5 times more than the chicken weight. For example, if you purchase 1,5 kg chicken you will need 4.5 – 5.2 liters of water. Do not forget that part of the water evaporates while boiling. Water should be cold. The main rule you should remember is to put chicken in cold water for cooking a delicious stock, while for cooking delicious meat, add boiling water.
