1Thoroughly clean the Pig's trotters by scrubbing them under cold running water. Use a knife to scrape off any remaining hair or impurities. Soak them in cold water for at least 30 minutes, changing the water once or twice.
2Place the cleaned Pig's trotters in a large pot and cover with fresh cold water. Add 20g of Ginger, 30g of Garlic, and 30g of Green onions. Bring to a rolling boil over high heat, then reduce heat and simmer for 15 minutes. This step helps remove impurities and strong odors. Drain the Pig's trotters and rinse them again under cold water.
