I got a piece of Beef Skirt in our local butchers, really cheap and a great cut for slow cooking, here's how I did it.
All this for a fiver!, I had to cut it into two to get it in the frying pan. Anyhow I browned it, while that was going on I cut up shallots and lined the slow cooker.
adding the meat as it was done, there's no need to cube it, after about 8 hours it will fall apart, and the larger pieces cook better anyway.
I then mixed beef stock with passata, adding carrot, garlic and a splash of Worcester Sauce to cover.
Now I can forget it for 8 hours.
