Preheat oven to 325 degrees. Make a meat-seasoning mixture by combining the
onion, bell pepper, garlic, salt, cayenne and black pepper. Poke holes in the
pork roast and push bits of the meat seasoning mixture into the holes to form
seasoning plugs all over the roast.
Place seasoned roast in a large bowl and pour the cane syrup or molasses over
the roast, turning the roast as needed to fully coat it.
Heat vegetable oil in a heavy skillet. Place roast in hot oil and brown it on
all sides. It browns fast because of the syrup; work quickly so you don't burn
the syrup-covered surface of the meat. Remove from heat.
Distribute flour evenly inside the oven-baking bag. Put browned roast in the
baking bag. Add water to the bag and close up the end of the bag with the
oven-baking bag tie or a knot.
Place roast in bag on a pan. Make 5 small slits in the top of the bag so the
steam from the roasting meat can escape. If desired, you can also stick a meat
thermometer into the roast through the bag so you can tell when the roast is
fully cooked. If using a meat thermometer, the temperature of the cooked Boston
butt must reach at least 160 degrees. The roast will cook in the bag for about 3
hours to reach tenderness and doneness.
Note: Some cooks don't like the flavor of garlic with pork. Omit the garlic from
the meat seasoning mixture, if desired.
