you would not cook your steak or fish for 2 hours, would you?
do cook pork for 2 hours, with some spices, and usually ginger takes away the pork smell, perhaps pork fat smell!
So "2 hours" doesn't apply to just "any meat", right?
ha ha! it still applies to any meat, cook such a long time, all kinds of meat become tender, except you will not cook steak and fish for a long time to make them tender!
