Tonkotsu ramen is a popular Japanese noodle soup known for its rich and creamy broth. The broth is made by simmering pork bones for several hours, which releases collagen and fat, giving it a distinctive white color and hearty flavor. This type of ramen typically features thin, straight noodles that complement the thick broth. Common toppings for tonkotsu ramen include sliced pork belly, green onions, and soft-boiled eggs. It is often served with nori (seaweed) and menma (bamboo shoots) for added texture and flavor. Tonkotsu ramen is a favorite among ramen enthusiasts for its depth and satisfying taste.
