Buta Kakuni is a traditional Japanese dish made from pork belly that is braised until tender. The meat is typically simmered in a mixture of soy sauce, sake, mirin, and sugar, which gives it a rich, savory flavor. This dish is often served with a soft-boiled egg and garnished with green onions or other vegetables. Originating from Nagasaki, Buta Kakuni is popular in various regions of Japan. It is commonly enjoyed as a comfort food and is often served with rice or as part of a larger meal. The slow cooking process allows the flavors to meld beautifully, resulting in a melt-in-your-mouth experience.
