Arrange beef short ribs in a shallow dish. Pour marinade over the ribs, ensuring even coverage. Cover and refrigerate for at least 30 minutes, or overnight for deeper flavour infusion.

Heat a small amount of neutral oil in a large oven-safe pot over medium-high heat. Sear short ribs on all sides until browned, about 2–3 minutes per side.

Pour remaining marinade over the seared ribs in the pot. Cover tightly and transfer to the preheated oven. Roast for 3 hours or until ribs are exceptionally tender.

Remove ribs from the pot and set aside. Mix cornstarch and water to form a slurry. Add to the pot with reserved cooking liquid and simmer over medium heat for approximately 5 minutes, stirring constantly until the glaze thickens.

Brush thickened glaze over the short ribs. Place under a hot grill (broiler) for 5–10 minutes until surface is caramelized and slightly crisp.

Let short ribs rest for 15 minutes to retain juiciness before slicing. Garnish with sliced green onions and sesame seeds before serving.
