If you have time, it's best to leave the meat in the fridge to marinate for 1 hour.
I couldn't wait, so I just put it in an oven dish with 2 finger widths of water, covered it with foil and put it in a max-preheated oven.
I waited for the water to come to a boil and lowered the heat to 302°F (150 °C). I baked for about 2 hours. The end result is unbelievably delicious meat that falls off the bone.
