1 Chicken (organic if possible) - if using a carcass from the Sunday roast skip the first section.
2 celery stalks
1 large onion
2 cloves garlic
10 black peppercorns
1-2 bay leaves
A few sprigs dry thyme
1 tbsp apple cider vinegar (helps to extract the nutrients from the bones)
Put all of the ingredients with skin still on (even the onions and garlic), giving the carrots and celery a wash before, into a large casserole and cover with cold water. Bring to the boil and leave to simmer for 2 hours. Remove the chicken and take the flesh off the bone.
