Cook's Illustrated had a recent article and recipe for indoor pulled pork barbecue. I had a great excuse to try it out with our recent snowstorm. The finished product had tons of flavor & bark. It's definitely worth getting the issue to try it out.
One of the secrets is halving the pork butt so that more surface area can turn into bark. Here's the pork after it was brined and then rubbed with mustard and a spice rub.
The finished product after a nice long time in the oven.
