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 typically served with various toppings like sliced pork, green onions, and soft-boiled eggs. Originating from Fukuoka on the island of Kyushu, tonkotsu ramen has gained popularity worldwide. It is often paired with thin, straight noodles that complement the thick broth. Many ramen shops offer their own variations, adding unique ingredients and flavors to this beloved dish.
