Stock. Yep, so glamorous. So this is the result of a chicken carcass and a turkey carcass cooked for two days on the woodstove until this was all that was left. Carcasses + water and that's it. None of the "add carrots and onions" and so on. Just water and carcasses. But when you add the carcasses DO NOT fail to add the skin and fat. First of all, those are not unhealthy fats but even you're adverse to the them, they're where a huge amount of the flavour hangs out. So, cook the stock with all of the bits intact and then toss them after. And you can skim off the fat once it' cooled but again, that's going to impact the flavour.
Of course, this not only made for the most delicious, "just add a pinch of salt and you're good to go" stock but also left us with chicken stew and dumplings, many meals for the faithful farm dog, and some love bone ash that's great for the garden and greenhouse.
Just be sure you have an epically large stock pot for the cooking. It makes a huge difference to have lots of water and a long, slow simmer.
