Toast chiles in your sauce pan at medium high heat. You want to get a little char on them.
Add 2 cups of the chicken broth. Bring to a boil. Lower the heat to medium low and simmer for 15 minutes. Remove from heat and set aside.
While the chile broth is simmering add 1 tbsp oil to a cast iron dutch oven over medium heat. Once hot, add garlic and onions. Cook until browned, about 5 minutes.
Add 1 cup water, cumin, chiles packed in adobo, fish sauce, adobo and oregano. Cook until fragrant (about 1 minutes)
Add the remaining chicken broth. Simmer for 10 minutes
Pour chiles and broth mix into a blender.
Add the other half you had been working on in the dutch oven to the blender. Blend until you have a mixed consistency. Set aside.
Season all the meat with salt and pepper. Add 2 tbsp oil to dutch over over medium high heat. When hot, brown the short ribs over medium high heat. Preheat oven to 275F.
Add mixture from the blender and two bay leaves. Bring to a boil then reduce heat to medium low.
Throw your roast into the mix. Cover loosely and cook in the preheated oven for about 3-4 hours. Or until meat is fork tender.
Remove the roast and short ribs from the sauce
The meat from the short ribs can be salvaged (this is the best part!) Discard the bay leaves.
Meat can be shredded for serving on the spot. Alternatively, if you have the patience, the meat will develop great flavor if you store it with the sauce in the refrigerator over night. I will keep for up to five days.
When you're ready to eat, shred the meat with a fork. Serve with corn tortillas and your favorite taco toppings (lettuce, tomato, onion, cilantro, avocado, sour cream).
