Step 1

To make the adobo sauce, toast the dried chiles in a cast iron skillet on both sides until fragrant and just browned. Remove from the skillet. Remove the stems and seeds. Place the chiles back in the skillet. Cover with water. Bring the water to a simmer. Cover and simmer for five minutes (or until tender). Drain the water and discard. Transfer the chiles to a blender or food processor. Add the remaining ingredients and process until smooth. Taste and adjust the salt level as desired.

Step 2

To prepare the marinade, combine the marinade ingredients in a bowl and mix well.

Step 3

Next, combine the marinade and pork in a zip-top bag or plastic container. Rub the marinade into the meat, making sure that there is marinade on all surfaces. Marinate in the refrigerator overnight.

Step 4

Remove all but two of the lower grates and preheat your YS640s to 350ºF. You will be using indirect and direct grilling.

Step 5

Remove the meat from the marinade, wiping off excess marinade. Using a standing skewer, thread the meat at varying intervals and once it is all threaded, place the skewer in the center of the lower rack, cooking for one hour at 350º. After cooking one hour, open the access door in the two-piece diffuser for direct grilling. Crank the YS640s up to 375º, push the heat plate all the way in and position the grates and skewer so that one side of the meat is exposed to the flames. Close the lid and cook for 15 minutes to get the sides closest to the flame charred a bit.

Step 6

Slide the grates and skewer away from the fire and use an electric carving knife to slice off part of the outside layer of meat using a small baking sheet to catch the meat. Rotate the meat and slide the grates and skewer back to cook and keep repeating the process until all the meat is cooked. Hold the pork in a warm place. Reheating the meat right before serving (or the following day) in a cast iron skillet will give it that extra bit of crispiness.

Step 7

Serve the pork wrapped in warm tortillas, with red onions, cilantro and cotija cheese.
