I am processing 9 birds this weekend for the first time and am looking to utilize as much of the bird as possible. Any tips for making bone broth? This will be my first time!
Also, any storage tips for the broth would be great!
For older birds I do this: slaughter bird, scald, pluck, eviscerate, chill. Then I come back after all the birds have been done and I remove the feet, neck, back, wings, wing tips, and skin. The skin is put into the freezer so that I can make schmaltz (chicken lard great for frying potatoes) and gribenes later. I also freeze the wings for later eating (but the wing tips are for stock).
Set the remaining parts aside temporarily (necks, feet, wing tips, and backs).
Cut the meat from the bone and pressure can the meat. (Pressure canned chicken looks like dog food but is absolutely delicious and is easy to make a meal from).
Now take all of the remaining stuff with bones (meatless carcass, neck, wing tips, back, etc) and roast the meat/bones in the oven. Once it is all roasted put it into the pressure cooker with the feet and cover with water AND some sort of acid such a Tablespoon of vinegar (the vinegar draws the minerals out of the bones for better bone broth).
Now pressure cook all the parts on high pressure for at least 1.5 hours. Strain the concoction and let the stock cool in the fridge. Once cooled, scrape the fat from the top of your broth and save it. That fat is schmaltz that is made as a byproduct from your making stock.
Then I pressure can the stock.
FYI you can absolutely add a few bay leaves, peppercorns, salt, onions etc to the pot before pressure cooking the roasted carcasses etc, it just depends on whether you want a straight chicken bone broth or a very seasoned stock.
As for amounts all I can tell you is this: I use about 6 chickens/parts/carcasses in a 16 qt cheap
Walmart pressure canner/cooker. If I break the bones up after roasting I can fit the all the chicken stock parts into the pot and cover the bones with 7.5 quarts of water. For me, this produces exactly 7 quarts of awesome chicken stock or bone broth.
I hope there is something here that you can use-
Good luck!
