Here's a fairly simple stock recipe I've been making for a few years. Usually I use saved chicken frames (the leftover bits from a whole chicken after cutting off the breasts and legs), but you can also get a whole chicken and cut it up into parts if you dont have anything saved. If you do use a mix with more meat, you can save the meat after making the stock for soups or salads. For each 1 lb of chicken meat and bon…
When there's enough, or I'm running out of space in the freezer, I plop all of that into a 8 or 12 qt stockpot, with a couple carrots, an onion and a couple stalks of celery. Enough water to be mostly full. (If it's hard to fit the frozen bits, pour near-boiling water from a kettle over it to fill the pot).
Bring to a boil, back off to a light simmer, let it go for a few hours.
Skim off the bulk of the fat, (reserve or not, I had 1/2 L for 3.5L of stock yesterday) Pour it out through a colander into a large bowl to strain the chunks, skim most of the fat out and put it in quart jars for freezing. If stored in the fridge, it's basically solid.
If you need more meaty bits, roast some wings. They've got the best mix of meat and collagen for stock.
I just toss all the solids, the meat is mostly tasteless at that point, though the dog likes the carrots. (and occasional bits of the meat)
