Place a 5½-quart (10-inch) Dutch oven over high heat. Add the chilies and toast for 3 minutes, or until fragrant. Remove from the pot and set aside.
Add 3 tablespoons oil to the pot and allow to heat. Add the beef and season with the salt. Sear for 5 minutes, stirring occasionally, until browned all over. Remove from the heat. Transfer the beef to the chilies and set aside. Meanwhile, continue to the next step.
Insert the wire rack into position 8. Set the oven to Slow Cook, Convection, High, for 3 hours and press Start to preheat. Meanwhile, continue to the next step.
Return the pot to high heat. Once hot, add 1 tablespoon oil. Add the onion and cook, stirring occasionally, for 3 minutes, or until softened. Add the garlic and cook for 1 minute. Add the spices, herbs, and sesame seeds, stirring until fragrant.
Add the tomatoes and scrape the bottom of the pot to release any browned bits. Stir in the stock, then return the beef and chilies to the pot. Bring to a boil, cover with the lid.
Once preheated, place the pot in the oven and slow cook for 3 hours.
The beef should be tender and easy to pull apart. If not, cook it longer.
Adjust the oven to Air Fry, Super Convection, 400°F, for 6 minutes and press Start. Meanwhile, separate the tortillas into three piles and wrap each in foil.
When the oven signals, place the tortilla parcels in the oven, directly on the wire rack and heat for 6 minutes. Meanwhile, continue to the next step.
Using a slotted spoon, transfer the beef to a bowl. Remove and discard the bay leaves, chilies, and cinnamon stick. Using 2 forks, shred the beef. Add ½ cup (4 fl oz) of the sauce from the pot, avoiding the fat from the surface, and stir to combine. Set aside.
Pass the sauce through a fine-mesh sieve. Skim off and reserve the oil from the surface in a bowl. Keep the sauce warm for serving.
Place 4 tortillas on the countertop, keeping the remaining tortillas wrapped to stay warm. Using tongs, dip one side of each tortilla into the reserved oil, then place oil side-down on the pizza pan. Sprinkle one half of each tortilla with some of the queso cotija and top with about ¼ cup shredded beef. Add a little onion and cilantro, then finish with more queso cotija. Fold the tortillas in half to enclose the filling.
Heat 1 teaspoon oil in a 12-inch cast iron skillet over medium heat. Add the 4 tacos and fry for 1 minute. Turn the tacos over, place the skillet in the oven and air fry for 6 minutes, until crisp and golden brown.
Repeat assembling and cooking the remaining tortillas.
Dip the tacos into the warm sauce and finish with a squeeze of fresh lime.
