Last year when i was working in Darfur, Sudan my South Africn and Zimbabwean co workers decided to throw an African style sheep BBQ to celebrate the completion of out Kitchen building project.
We purchased a lamb from a local merchant in the town of Nyala which is the capital of southern Darfur http://en.wikipedia.org/wiki/Nyala,_Sudan
The lamb was killed in the Local Muslim fashion otherwise our Islamic bretherin would not eat it or even touch the meat.
We made a combination of spices and herbs mixed with coca cola and injected it into the meat by way of a syringe given to us by the medical staff.
Next we wired the Lamb to the rack and rubbed in a bit more of the coke and spice concoction,
I watched the South African guys build the fire and when the coals were just right They placed the lamb on the Spit and flipped the switch on the electric motor to operated the turning of the spit.
Periodically we would check the heat of the coals and adjust the flame/heat if necessary. I cannot remember the amount of time it took to cook this lamb but after it was done the boys from RSA cut it up in the new kitchen and the Lamb was served with Salad, Local bread, zimbabwe style corn mush, tomato sauce and a few other local dishes. all in all a pretty tasty way to celebrate the new kitchen facilities.
Darfur was an interesting place and we were a mixed group of guys from places like Canada, USA, Russia, India, and all of Africa.
I had a good time there and would probably still be working there had the Sudanese government not kicked out all of the american contractors.
Attached are a few pics of the BBQ process.
