Make sure meat is defrosted and cut into large chunks. Place in a bag with marinade made from the sweet red wine, sugar, soy sauce, half a head of garlic and half the herbs.
When ready to cook, heat the pot over hot coals. Add lamb fat and onions then beef. Stir to sear the meat.
Now peel and chop the rest of the vegetables, throw the heads of garlic in whole, no peeling necessary. Pour over a bottle of wine and add water until the ingredients are covered.
Cover with lid and let cook on the coals for at least 1 1/2 hours while you go out horseback riding like Jamie does in the video below. Check on the stew and if it needs more liquid add water or more wine, if too much liquid leave it uncovered for a bit before eating.
