I used pork shoulder.
Marinate pork with salt and black pepper for 10 mins.
Put pork on grill in oven. Turn to 220 degree C. Grill for 5 mins.
Brush butter on both sides. And keep on grilling for 30 mins. Brush butter and flip over every 10 mins.
After grilling, place pork in the plate.
Heat the pan on stove. Add in 2 tsp BBQ sauce, 1/2 tsp honey and 1/2 tsp water. Turn to low heat and keep stirring till sauce becomes condensed.
Pour sauce over pork.
