Tonkotsu is a rich and creamy Japanese ramen broth made primarily from pork bones. The bones are simmered for many hours, often over 12, to extract collagen and fat, resulting in a milky-white soup. This hearty broth is known for its deep flavor and is a staple in many ramen shops. Typically served with chashu (braised pork belly), menma (bamboo shoots), and green onions, tonkotsu ramen is often accompanied by nori (seaweed) and a soft-boiled egg. Its unique taste and texture have made it a favorite among ramen enthusiasts worldwide.
