This is a long-time favorite that is still requested, only whisky will do for this, and yes 3 bunches of green onions! --- this roast must be cooked in a low-temperature oven for about 3 hours :)
- Set oven to 300 degrees.
- Heat oil in a large oven-proof pot or Dutch oven over high heat.
- Season roast with salt, pepper and garlic powder on all sides.
- Brown the pork roast on all sides in hot oil, turning often (this should take about 15-18 minutes).
- Remove the pot from heat, and cool the roast enough to handle.
- While still in the pot, spread the hoisin sauce over the browned roast (or you can remove the roast to a plate and return back in the pot).
- Sprinkle the green onions over the roast in the pot and cover with a lid.
- Place the roast in the oven.
- Cook until pork is very tender when pierced with a fork (about 3 hours) adding water to the pot about 1/4-cup at a time if mixture is dry.
- Remove the pot from the oven and transfer pork to a cutting board; tent with foil and let stand for 20 minutes.
- Meanwhile spoon off fat from the pan juices.
- Stir in whiskey and 3/4 cup water into juices; boil 2 minutes on top of stove, adding a small amount of water in if the sauce is too thick, or if sauce is too thin, boil and reduce.
- Slice the pork thinly, pour the sauce over and serve.
