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.
Do you have blocks (frozen zip bags?) of stock in the freezer, and just toss one in the crock pot when you need some?
I use mason jars. Not great because they can crack if too full, but they’re easy to organize and measure. Each jar is about 1.5 cups of stock, or more if I dilute with water to make broth.
