Whisk together all ingredients except the pork in a medium glass bowl.
Place the meat into a large zip top bag.
Pour the marinade over the meat and turn to cover.
Roll the bag to remove as much air as possible and zip the top to close.
Place bag in a small glass bowl and refrigerate for 8 hours to overnight.
Cooking sous vide
When ready to cook, set up the sous vide water bath to 150 degrees.
Using the water immersion technique, remove the air from the zip top bag containing the meat and marinade.
Place into the water bath, cover with foil or plastic wrap, and cook for 8 hours.After 4 hours, set the temperature to 145 degrees if you are planning to pull the pork.
Finish with smoker
Preheat the barbeque on High.
Prepare the smoker box with apple wood chips.
Remove the meat from the water bath and reserve the marinade.
Place the meat on the grate within the smoker and brush with marinade.
Smoke for 20 minutes over indirect high heat to create the glaze and crust.
Remove from the smoker and allow to rest 10 minutes covered lightly with foil.
Serving Option 1:
Slice the meat into ⅛ inch thick slices and serve with hot mustard, sesame seeds, and thinly sliced scallions.
Serving Option 2:
Pull the meat with two forks and serve on buns as pulled pork with additional hoisin sauce, sriracha slaw, etc.
Serving Option 3:
Slice the meat into ¼ inch slices and julienne or dice for use in fried rice, singapore noodles, etc.
Notes
Another way to potentially color the meat the typical bright red - add sweet and sour sauce to the marinade. I will give that a try at some point in the future when I do this recipe on a pork tenderloin.
