I made some turkey stock from the carcass of the roasted bird we had this week. I threw it in to tthe crock pot with some onion, garlic and a couple carrots, cut the bones a bit to leach the marrow, added water half way up and cooked it on high all day. It's awsome! I stuck it in the fridge to cool overnight, and will reduce it by about a third tomorrow, add some leftover meat and freeze it.
I had never made stock this way before - I think this will be my new method forever more...
