Do I need to roast my spatchcocked chicken backs prior to making stock?
I think the answer is yes.. but wanted to ask.
I've gotten in the practice of taking the backs out of my chickens before I roast.....
Should I now roast these backs for 45 mins or so - before I use them to make chicken stock?
For that matter should I roast all the bones before I throw them in the stock pot
You don't have to, but it helps create a more developed flavour in the stock. And 45 minutes is probably a bit long for the bones. I just crank my oven to high, and roast them until they are golden brown and sizzling, probably in the 15-20 minute range. I also generally add my mirepoix at this point and roast the vegetables as well.
All depends on the flavour you want out of the stock, conventional wisdom is that yes you should roast them, but there are some lighter stock applications where unroasted is preferred.
Typically I would always roast all bones for stock.
You don't have to, but it does make the flavour different. Stock made from roasted chicken will be darker and have a more intense roasted flavour, that made from uncooked will be paler and have a more neutral flavour.
So basically, it depends on what you want to do with the stock when you've made it.
I don't roast my chicken backs for stock but now that you mention it, I DO roast my turkey parts for turkey stock. The turkey is a sort of a big deal, semi-annual event, and I want a "rich" stock for gravy, but the chicken parts are in almost constant rotation. Bone a chicken? Put the bones in the freezer. When I need stock, or more room in the freezer, they go in a the pot for stock.
I will try roasting them next time, if it doesn't make it a bigger ordeal.
What it comes down to is - what flavor do you want in the stock?
I'm quite happy with a stock made from unroasted parts, even one made with a left over carcass. Come to think of it, I usually do both.
Often when preparing a large bird I use the legs and thighs and wings for a dark meat stew. I bone the breasts for another use. The breast bones, backbones, wingtips, and neck go into a stockpot. After the meal, the dark meat bones go back into the pot, for another hour or 2. The result is roughly a quart of well gelled stock.
I could roast the backbones, etc, but that's another step in already busy supper preparation.
