You need a pot that is big enough to fit your chicken breast. Fill the saucepan with water, so that when you add the chicken it will be covered by at least 2 inches of water.
Bring the water to the boil, add the chicken and pop the lid back on. Remove from the heat.
Let the chicken poach in the hot water without removing the lid for 30 mins. After this time your chicken should be cooked. You can double check the chicken is cooked by checking the internal temperature with a meat thermometer, it is cooked if the temperature is 76 degrees Celsius or above.
If your chicken is not cooked after this time (if your pot did not hold its heat well or if the chicken breasts are large this could occur) reutn the pot to the heat, and simmer until cooked.
Remove the chicken from the pot, and reserve the poaching liquid. Roughly chop the poached chicken.
Puree with ¾ cup liquid add ¼ cup at a time to blender or a food processor until a smooth chicken puree is acheived.
Notes
Yield will be approximately 2 cups of chicken puree.
Chicken breasts or chicken thighs can be used
The poaching liquid can be flavoured with lemon slices, or herbs such as thyme, bay leaves or a bouquet garni.
Although I have used chicken breast you can also use boneless skinless chicken thighs in this recipe, brown meat is higher in iron which can make it a could choice for homemade chicken baby food.
Do not feel tempted to add salt to the water when poaching the chicken, this is fo two reasons, firstly baby food should not be salted, and secondly salted liquids boil at different temperatures to unsalted liquids.
