Pork belly ramen is a popular Japanese dish that features tender slices of pork belly in a flavorful broth with noodles and vegetables. The pork belly is first marinated in a mixture of soy sauce, mirin, and sake, then seared until crispy. The broth is made with a combination of chicken and pork bones, soy sauce, and other seasonings. The result is a deliciously rich and savory ramen that is perfect for a cold day.
