I found this online the other day and it was credited to Nigella Lawson. I found that I disagreed with some of the assertions made by both the re-poster and Nigella herself. Now I would never accuse such a sexy woman of being wrong, but I will say that the way I did things turned out great. This recipe reflects my own variation of the original recipe.
After cooking and eating this dish I have concluded that this is what I believe to be "broasted". By that I mean the meat has been both braised and roasted, not fried in a pressure cooker. The end result is chicken that is so tender, you can almost spread it like schmear on a warm bagel.
The 2 hour cooking time includes the extra 40 minutes I let it sit in the oven after I turned it off.
In case you are not familiar with Spanish Chorizo, it's not like the Mexican variety. It is a hard sausage, much like a salami or pepperoni. It's usually seasoned with paprika, and is made from chunks of pork, not ground meat. I have found it in the deli section of my local grocery store.
