• Extended cooking gently breaks down connective tissue, resulting in very tender meat.

• The lower heat allows fat to render slowly keeping the meat incredibly moist.

• Cooking for a longer time at a lower temp gives seasonings and spices a chance to deeply penetrate the meat,

• Slow roasting yields incredibly rich, complex flavors as juices caramelize and reduce.

• Lower temperature means less risk of burning or overcooking the exterior before the interior is done.
