Pernil (Puerto Rican Roast Pork Shoulder)

Puerto Rico's festive roast: skin-on pork shoulder marinated overnight in garlic, oregano and vinegar adobo, slow-roasted until fork-tender under shatteringly crisp skin.

About servingsCook pork all the way through (at least 71 °C in the thickest part). For this dish it needs to reach about 90 °C to become tender enough to pull apart.

Method

  1. Pat the pork thoroughly dry with kitchen paper. With a sharp knife, score the skin in a 2 cm criss-cross pattern, cutting through the skin and fat but not into the meat. On the exposed meat, stab deep holes about 2 cm deep and 3 cm apart with the tip of the knife; the marinade will go into these.

  2. In a mortar, pound the garlic with most of the salt to a smooth paste, then add the pepper, oregano and cumin and pound again. Stir in the olive oil and vinegar to make a thick adobo. No mortar? Grate or very finely mince the garlic and mix everything in a bowl.

  3. Push the adobo into the holes with your fingers and rub it all over the meat. Keep the marinade off the skin: leave the skin dry and simply sprinkle it evenly with the remaining salt. Put the pork skin side up in a container, cover and refrigerate for (overnight). Take it out 1 hour before roasting. Wash your hands and tools right after handling raw pork.

  4. Preheat the oven to 160 °C (oven). Put the pork skin side up in a 25×20 cm roasting dish and pour the water into the bottom (not over the skin). Cover with foil and roast for .

  5. Remove the foil and roast for more, until a fork slides in easily and the meat pulls apart along the grain. If you have a thermometer, around 90 °C in the thickest part means pull-apart tender (it must reach at least 71 °C to be safe). If the pan juices dry out and start to burn, add a splash of water.

  6. Turn the oven up to 230 °C (oven) and roast for more, until the skin puffs up and crackles (this crisp skin is called cuerito). Watch closely in the last 5 minutes and take it out as soon as any spots start to blacken.

  7. Move the pork to a board and rest it for so the juices settle back into the meat. Break the crackling into pieces, pull or slice the meat and spoon over the pan juices. For the classic plate, serve with rice, arroz con gandules (rice with pigeon peas) and fried plantains.

Cook's tip

Bone-in is juiciest, but boneless shoulder works too (cut the roasting time by 10 to 15%). If the skin isn't crisp enough, finish it under the grill (broiler) for 2 to 3 minutes without taking your eyes off it. Sour orange juice (naranja agria) can replace the vinegar for an equally traditional flavour.

Cooking it at camp

Roast it on a lidded kettle grill using indirect heat: coals on one side, the pork in a metal tray on the other, lid on, at 150 to 160 °C, for about the same time as at home. At the end, move it over the coals to crisp the skin, watching all the time so it doesn't burn. Keep the marinating pork below 5 °C in the cooler.
