essentials
I use a pressure cooker for making stock; it only takes an hour once it is up to pressure. Alternatively you can keep a slow rolling simmer in a large stock pot for 3-4 hours (although I'm not really qualified to say). You can use bones of any animal - I follow the same process regardless of type of bones used.
2 large carrots
2 -3 large onions
4-5 sticks of celery
1 tbsp black peppercorns
1 tbsp salt
3 bay leaves
2 sprigs of thyme
1 leek
1.5kg chicken bones
bunch of parsley (use roots if you are picking from your garden)
Optional items:
Parmesan cheese rind (I throw these in the freezer once I finish the cheese block)
1 punnet of mushrooms
