Start by seasoning the short ribs with salt and black pepper on all sides. Let them sit for 30 minutes to allow the flavors to absorb. Meanwhile, preheat the oven to 325°F (160°C).
Add beef tallow or lard into a large pan. Heat it over medium heat. Add the short ribs and sear on all sides for 2 minutes until golden brown.
Add the short ribs to a Dutch oven. Pour in the chicken bone broth and bring it to a boil. Remove from the heat and put it in the preheated oven for about 2 hours, or until the short ribs are tender and fall off the bone.
