Here's a step-by-step tutorial on how to cook beef short ribs:
1. Preheat the oven to 325 degrees Fahrenheit.
2. Pat the short ribs dry with a paper towel, then season them on both sides with salt and pepper. Dredge them in flour to finish.
3. Heat the oil in a pot over high heat. Once it’s hot, add the short ribs and brown on all sides. Set aside.
4. Add onion and garlic to the skillet; cook and stir until onion is tender, about 5 minutes.
5. Pour in beer while scraping the browned bits of food off the bottom of the pan. Pour in beef stock.
6. Lay the beef in a baking dish with the bone side down. Put the ribs close together and tightly cover with aluminum foil.
7. Cook for 3 1/2 to 4 hours, or until the meat is tender and the bone starts to come away from it.
