How long do you cook duck?

Whole duck? Duck breast? Thighs? They all take different amount of time and will vary depending on methods.

I did a Peking Duck just before Christmas...the roasting part was just over an hour. (the skin prep and hanging was 11 hours ! ! ! )

It depends on how you cook it -- here's a great method for slow roast duck: http://www.food52.com/recipes/9115_slow_roast_duck
