Creating Caramelized Slow Roast Asian Beef Short Rib is an enjoyable process that ensures delicious results if you follow these steps:

1. Prep the Ribs: Pat the beef short ribs dry using paper towels, and set aside.
2. Make the Marinade: In a bowl, combine soy sauce, brown sugar, honey, rice vinegar, sesame oil, garlic, ginger, and sriracha sauce if using. Whisk until sugar dissolves.
3. Marinate the Ribs: Place the short ribs in a large resealable bag or dish. Pour the marinade over the ribs, ensuring they are evenly coated. Seal and refrigerate for at least 2 hours, or overnight for best results.
4. Preheat Oven: When ready to cook, preheat your oven to 300°F (150°C).
5. Sear the Ribs: In a large oven-safe skillet or roasting pan, heat a bit of oil over medium-high heat. Sear the ribs on all sides until browned, approximately 3-4 minutes per side.
6. Add Marinade: Once seared, pour the marinade over the ribs in the pan, making sure they are well coated.
7. Cover and Roast: Cover the pan tightly with aluminum foil or a lid. Roast in the preheated oven for 3 to 4 hours, until the ribs are fork-tender.
8. Caramelize the Sauce: After the ribs are cooked, remove them from the oven. Take out the ribs and keep them warm. Place the pan with the sauce on the stovetop over medium heat.
9. Thicken the Sauce: In a small bowl, mix cornstarch and water until smooth. Gradually add this mixture to the sauce, stirring constantly until it thickens.
10. Glaze the Ribs: Return the ribs to the pan, tossing gently to coat them in the thickened sauce. Let them cook for an additional 5-10 minutes on low heat to absorb more flavors.
11. Serve and Garnish: Remove from heat, and sprinkle sesame seeds and chopped cilantro on top for garnish.

By following these simple yet thorough steps, you will create a dish that dazzles not only the eyes but also the palate.
