Add the stock and milk slowly, a little bit by little bit and
continue to stir in a figure of 8 shape while the soup starts to
thickener cold water. Set aside. Use a fork to shred chicken from
the bone.
Once the soup has thickened nicely, add the salt and then the
onion /garlic powder if you wish – this is optional.
Add a little freshly cracked black pepper and more salt if
necessary.
