Chashu pork is a popular Japanese dish made from tender, melt-in-your-mouth braised pork belly. The pork is marinated in a flavorful soy sauce-based sauce and slow-cooked until it becomes incredibly tender. It is often used as a topping for ramen or served as a side dish with rice. The rich and savory flavors of the chashu pork make it a delicious addition to any meal.
