Start by seasoning the short ribs with salt and black pepper on all sides. Let them sit for about 30 minutes. Meanwhile, preheat the oven to 325°F (160°C).
Add beef tallow or lard into a large pan. Heat it over medium heat, and then add the short ribs and sear on all sides for 2 minutes until golden brown.
Add all 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 – until the short ribs are tender and fall off the bone.
