I fit two 2lb-ish birds into a Crock-pot and set to high for 6 hours. I then removed the meat from the bones, which just more or less fell off, then put all the bones back in until it was a total of 24 hours. I put a tablespoon of apple cider vinegar at the start. 1 onion and some pre minced garlic from a jar. Also, some salt but that’s it. One problem is though, the reason it stopped exactly at 24 hours was coincidence. The power went out for 6 hours. To try and save the bone broth, I did not lift the Crock-pot lid and I put it into the oven to help protect it. When the power came back on, I immediately dumped what was in the Crock-pot through a strainer (one meant for spaghetti, so not the greatest) into a Tupperware and then directly into the fridge. So, is what I have even considered bone broth? Is there a decent amount of collagen in there? Did it potentially spoil and needs to be thrown away?
