Many moons ago, I published my recipe for pernil, the delicious Puerto Rican roasted pork butt/shoulder. Recently, I had a whole Saturday afternoon to try a longer and slower cooking method for my bone-in pork butt. I have to tell you, if you have the time I would advise cooking it this way as you will have meat absolutely dripping moist and falling off the bone. The quicker method in my earlier recipe is a very good way of cooking the pork if you dont have 8-9 hours to kill waiting to tear into the pernil. But, if you do remember to put your pork in by 11AM, you will not be disappointed by the results of low and slow cooking. I am cutting and pasting the old pernil recipe here and adding my alternative Low and Slow cooking time. I hope youll give it a shot and let me know what you think! Remember to allow your pernil to marinate overnight for the best results!

A five-to-ten-pound bone-in pork shoulder requires serious oven space and a roasting pan with high enough sides to prevent liquid from spilling over onto your heating elements during the initial high-heat phase. Because this recipe demands an initial blast at 475 degrees Fahrenheit followed by eight to nine hours at 275 degrees Fahrenheit, standard baking sheets will not suffice and will warp under the thermal shock. Anyone attempting this cut without a heavy-duty roasting pan and a tight seal of aluminum foil will find the meat dries out long before the connective tissue breaks down.
Piercing the skin and flesh to drive garlic slices deep into the muscle fibers serves a structural purpose beyond mere seasoning, as these channels allow the acidic sour orange marinade to penetrate the dense interior of the shoulder. Sour orange juice provides the necessary acidity to break down tough collagen proteins, but if bottled sour orange is unavailable, combining standard sweet orange juice with fresh lime juice at a one-to-one ratio yields a functionally similar pH level. Mashing the garlic into a smooth paste with coarse salt in a mortar and pestle rather than simply slicing it ensures the aromatics distribute evenly throughout the meat instead of falling out during the lengthy roasting process.
Managing moisture is critical when alternating between dry heat and braising environments over a nine-hour span, which is why maintaining a half-inch of liquid at the bottom of the roasting pan protects the lower muscles from scorching while steam keeps the upper layers hydrated. Allowing the pork skin to remain exposed during the final thirty to forty minutes of cooking is non-negotiable if you expect to achieve the brittle, crackling exterior known as chicharrón. Removing the foil too early, however, will dehydrate the fat cap prematurely and turn the exterior leathery rather than crisp.
Resting the roasted shoulder for twenty to thirty minutes before carving allows the internal muscle fibers to relax and reabsorb the rendered juices that would otherwise pool instantly on the cutting board. Slicing the meat too soon after it emerges from a 275-degree oven causes the internal moisture to bleed out, resulting in dry strands regardless of how long the pork cooked. Reserve any remaining pan drippings separately to spoon over individual servings, as the rendered fat carries the concentrated essence of the garlic, adobo, and citrus marinade.
