I cook chicken a little past the USDA recommended temperatures to ensure that Marcia doesn't see anything pink in there. But I still want to pull the breast before the legs. That can't be done with a spatchcocked bird so I've been using a technique that Barry (Chef Barry or just CB) Martin showed me a few years ago.
Lay the bird on its back and peer up into the breast cavity to locate the joint in the ribs where it looks like some go with the breast and some go with the back. Cut along that V-shaped "seam" with sheers and when you get to the front
just turn 90° and cut through the
spine difficult joint that's left (I think it's the long end of the wishbone).
That removes the back from the breast, leaving only the breast and wings with the body cavity open because the back is gone.
You don't have to do any cutting on the other piece. It's the complete back and the two thighs and legs.
Now you can pull the breast at one temperature and the dark meat at another.
I was reluctant to try it at first 'cause it didn't seem as though I had complete instructions—but I actually had all I needed. It's just that there's not much to it.
What the heck. Give it a try. So what if it doesn't turn out exactly the way you wanted. It'll still cook up.
