Tonkotsu ramen is a rich and creamy pork-based soup that originated in Fukuoka, Japan. The broth is made by simmering pork bones for hours until the collagen and marrow break down, creating a thick and flavorful soup. The noodles are typically thin and straight, and the toppings can include sliced pork belly, soft-boiled eggs, green onions, and nori seaweed. This hearty and satisfying dish is perfect for cold winter nights.
