Cut the beef chuck roast into 1 inch cubes. Arrange the beef chuck roast and short ribs on a baking sheet and coat each piece with salt. Place in the refrigerator for at least 4 hours, up to overnight.
Add the ancho chilies to a medium sized heat resistant bowl and cover with warm water and soak until softened, between 10-15 minutes. Once softened, remove the stems and seeds and set the chilies aside.
In a small skillet over medium heat, toast the cinnamon stick, coriander seeds and peppercorns until fragrant, about 2 minutes. Transfer the toasted spices to a spice grinder containing the guajillo chili powder, allspice, bay leaves, and oregano and grind into a fine powder.
Preheat the oven to 300°F and remove the salted meat from the refrigerator. Using paper towels pat the meat dry. In a large Dutch oven (or cast iron skillet), heat 1/4 cup of a neutral oil on medium-high heat. When the oil shimmers, add the seasoned meat and fry until golden brown, working in batches to avoid overcrowding the pot. Remove the seared meat from the oven/skillet and set aside.
Add the onion and tomatoes and cook until the onion becomes translucent. Add the garlic with a bit of salt and cook until fragrant. Add the ground spices and continue cooking until aromatic.
Add the apple cider vinegar, water, seared meat, and chilies to the oven and bring to a boil, then reduce the heat to medium-low and cover. Simmer until the stew begins to thicken and the chilies are completely softened. Cover the stew with the foil or banana leaves, then place the lid on top. Transfer the stew to the oven and cook for 90 minutes. At that point, remove from the oven and blend the chilies. Place the blended chilies back into the stew and place back in the oven and cook until the meat is tender, approximately 90 minutes - 2 hours. If after 3 - 4 hours, the meat has some resistance, cover and cook longer, until very tender. Remove the stew from the oven and discard the foil or banana leaves, then remove the meat from the pot and transfer to a large bowl. Use a pair of tongs or forks, shred the meat. Reserve the broth (consomé).
