For this recipe you will need a Doufeu. Le Creuset make really good ones, but they are a bit expensive. If you can afford it, it is so worth it; the meat melts in your mouth and is so full of flavour, plus it is the healthiest way to cook any joint which you would normally roast. If you do not have a Doufeu, you can achieve the same results using an ordinary roasting tray sealed with foil or casserole with a lid and cooked in the oven at a low heat for several hours, you will need to use oil instead of wine. Unfortunately, this will make the recipe much less healthy.
