Last weekend I tried a chicken recipe with chorizo sausage stuffed under the skin. I loved the flavor of it, but I'm not too handy with whole chickens and didn't get any sausage flavor on the thighs or legs.
This weekend I decided to try chicken breasts alone. Instead of sliding the chorizo under the skin, I went with bone-in but skinless breasts, and slashed the meat against the grain to hold the sausage, hoping the sausage grease would permeate the meat better. I also wondered if I should cook the sausage in a frypan a bit first, to get rid of excess grease and ensure the chorizo was fully cooked. Since I had two breasts, I did one each way; the one on the left is stuffed with raw sausage and the one on the right with cooked (you can't really see a difference, I used a toothpick in one to keep track).
Cooked to 165:
The chorizo didn't seem any different in either breast, BUT the breast with the raw sausage absorbed a lot more flavor (more grease!), plus it was easier to work with and one less dirty pan.
Because the chorizo sat in slits in the top of the breasts, I knew I wouldn't be flipping them so chose indirect head. Going skinless was a mistake, the surface of the chicken was a bit dry and leathery (still perfectly edible, however). Next time I'll either peel the skin back, slash the meat, stuff, and lay the skin back over the breast; or just slash through the skin and stuff (they do look kinda neat with the bright red slashes).
It's getting closer.
Live fast, die young, and leave a well-marbled corpse.
