The ingredient list itemizes a boneless pork shoulder butt roast, but it fails to specify muscle structure. Pork shoulder contains significant intermuscular fat and collagen, which require moist heat and sustained low temperatures to break down into gelatin. Browning the roast in a Dutch oven initiates the Maillard reaction on the surface proteins, establishing savory depth before the meat enters the water bath. Simmering the cut for 2-1/2 to 3 hours ensures the internal temperature reaches the threshold where connective tissues dissolve. Pulling the pork apart requires the meat to be cooled first; handling hot fibers shreds them unevenly and dries out the protein.
Combining beef broth, condensed tomato soup, cider vinegar, and steak sauce creates a hybrid braising liquid that relies on a lengthy reduction phase. Simmering the combined sauce ingredients uncovered for 1-1/2 to 2 hours evaporates excess moisture, concentrating the sugars from the tomato soup and steak sauce. Failing to reduce the sauce adequately leaves a watery mixture that immediately compromises the structural integrity of the sandwich buns. Maintaining a medium-low heat during this reduction prevents scorching the tomato solids along the bottom and sides of the saucepan.
Once the sauce thickens, introducing the shredded pork for a final 30-minute simmer allows the lean muscle fibers to absorb the surrounding acids and spices. Splitting 12 to 14 sandwich buns just prior to service prevents moisture migration from the heavy meat filling. Cooks frequently ruin this preparation by failing to drain the initial cooking juices from the Dutch oven, which dilutes the carefully balanced acidity of the secondary sauce. Storing any leftover shredded pork submerged in its sauce in the refrigerator maintains moisture retention for up to four days.
