First, remove any excess fat from the outside of each piece of oxtail and season with a good dose of your favorite BBQ seasoning. Let it rest for a couple of minutes.
While having the oxtail hang out, prepare the cooker. You can use smoker of any kind of Smoker for this recipe. Fire it up and bring the temp to 275 degrees.
Place the oxtails on the grate and put the lid back on.
After 1 1/2 hour check it and flip it over to cook evenly on both sides for another 30 minutes. Then take it out the smoker.
Using an iron pot, pour in the braising liquid, then set the pieces of oxtail down the braising liquid. Pour down the remaining braising liquid on top of the oxtails. Cover the pot with aluminum foil to trap all the steam in there. Put it back in the smoker, check it every hour.
After 2 1/2 hour it should all be tender. Once its all tender, remove the pot from the smoker. Get the oxtails out from the braising liquid, put it in a platter. Cover the platter with aluminum foil to rest for couple of minutes.
Strain the braising liquid to use as the sauce.
Place the oxtails on top of the rice in a platter. Put the sauce over the top. Garnish with slice green onions. This will definitely put a smile on your face.
