Slice the pork shoulder into about ½ inch slices, then transfer to a large bowl.
In a bowl, combine the achiote powder, chili powder, Tajin seasoning, garlic powder, oregano, cumin, salt, pepper, chipotle adobe sauce, jalapeño wine, vinegar, and pineapple juice. Whisk until smooth. Stir in cilantro, garlic and habanero.
Pour the marinade over the pork making sure all pieces are covered. Marinate for 12+ hours.
COOKING PREP
Turn Traeger on smoke – establish fire, then turn to 350°.
Skin the pineapples. This recipe will make 3 Al Pastor “towers”, so cut three 1” base pieces, and then cut the rest of the pineapples into thinner ¼” slices. (I only used about 1 ½ of the pineapples.)
Remove the pork from the refrigerator and add the ½ lime juice. Toss to distribute lime.
Use a baking sheet to assemble towers. Place the 3 base pineapple slices down, and then stick 1 skewer into each, pointed end up. Layer the pork and pineapple evenly between the three stacks, using a 2 layers pork to 1 layer pineapple pattern, topping with 2 pieces of pineapple. Finish towers by sticking more skewers down into the towers to help sturdy them, making sure to place one down the center. Clip the tops of the skewers off with wire clippers so that they fit in the Traeger.
Cook for about 2 to 3 hours at 350°F. The towers may fall over which will not affect the cooking time. Remove when internal temp 140°. Rest meat for 10 minutes. Remove all skewers except the middle one, carve off thin slices of the pork & roasted pineapple.
Assemble with corn and flour tortillas, onion, cilantro, lettuce, queso fresco, avocado and fresh salsa
