Boil the ribs for about 10 minutes until dark brown bubbles appear. Then remove the pot from the heat, discard the water, and refill with fresh water to boil.
When the ribs are ready, heat a medium pan to grill the cabbage and garlic. Grill the cabbage until it develops a smoky aroma and turns brown on both sides.
Cover the pot and let everything simmer until the cabbage becomes tender and releases its flavors into the broth. If you prefer the cabbage to stay a bit crunchy, simmer it for just about 10 minutes.
