My wife bought a rotisserie chicken, so we made stock with the carcass. Its just so good to get 5 liters of stock from what would be garbage. Tattler lids worked well today, only one didn't seal. I don't normally do that well. Easier to get them to seal in a water bath.
Making stock from rotisserie carcasses is so much fun! I freeze mine rather than can, but these look quite good!
I usually use a brew bag for cooking the carcasses in; they're designed to be heat resistant and it makes separating the bones from the stock so much easier.
