I'm making broth using beef bones and vegetables. I started by roasting 3lbs of bones with a bit of meat on them in the oven. Then I added them to a large stockpot, covered with cold water, and added 2T of apple cider vinegar. After 30 minutes rest, I added my veggies (celery, onions, and carrots) and seasonings to the pot, and brought it to a rapid boil. I turned it down to a simmer, where it's been for just the past 30 or so minutes.
I started this process late at night, knowing that it takes 12-24 hours of simmer time for a good stock. But I didn't realize my family is not comfortable with me leaving the stove on all night, so I'll have to turn the stove off in about 2 hours.
How can I save my stock? Can I leave the covered pot on the stove (in the off position) for a couple hours? Should I put the whole pot in the fridge? Or should I take it off the heat now and do something else with it?
