Braised Pork Belly (Buta Kakuni)

Place pork belly, ginger (for boiling), green onions (white parts) and water (for boiling) in a large pot. Bring to a boil over high heat, then reduce heat to medium-low and simmer for 30 minutes. Drain the pork belly, rinse under cold water, and cut into 4-5cm cubes if not already. This step removes impurities and excess fat.
