Buta No Kakuni Braised Pork Belly Advanced
Japan — kakuni influenced by Chinese Hong-shao rou via Nagasaki trade routes
Kakuni (角煮, square simmered) is Japan's definitive long-braised pork belly — thick cubes of pork belly braised for 2-4 hours in soy sauce, mirin, sake, and sugar until the fat becomes completely unctuous and the meat is falling-tender. The Nagasaki style (Shippoku ryori cuisine) uses slightly different seasonings with Chinese influence (five-spice sometimes added). The Okinawan Rafute version adds awamori (Okinawan distilled spirit) and darker sugar. The central technique challenge: the fat layer must be completely rendered and become gelatinous (not greasy) while the meat remains intact. Pre-boiling in plain water for 30-60 minutes removes excess fat before seasoning.
