Okinawa (Ryukyu Islands). The preparation developed from Chinese Hong Shao Rou influences absorbed through the Ryukyu Kingdom's trade with China. Awamori substitution made it distinctly Okinawan.
Rafute is Okinawa's signature braised pork belly preparation — thick slabs of skin-on pork belly simmered for hours in awamori (Okinawan rice spirit), soy sauce, sugar, and dashi until the skin and fat become completely tender and the meat is deeply caramelised. Unlike Japanese kakuni (cubed pork belly braised in sake and soy), rafute uses awamori as its primary spirit — the distilled rice alcohol penetrates the fat and skin differently than sake's lower ABV. Rafute is inseparable from Okinawan identity and from the island's tradition of eating the entire pig — from ear to trotter — without waste.
Rafute delivers a profound combination: the deep caramelised sweetness of the soy-sugar glaze, the penetrating warmth of the awamori, and the unctuousness of fully rendered pork fat and gelatinised skin. The skin's collagen has transformed into smooth gelatin that melts immediately. The meat is deeply seasoned throughout. The overall effect is rich, warming, and deeply satisfying — the ancestral Okinawan pig culture in a single preparation.
The pork belly is cut in large blocks (8–10cm square) with skin on. Initial blanching (30 minutes) removes excess fat and blood. The braising liquid: awamori (or strong sake), soy sauce, sugar or brown sugar, and kombu dashi — the awamori is used generously (200–300ml per batch). The braise is long: 2–3 hours at a gentle simmer until the skin is completely tender and the fat is translucent. Reduce the braising liquid to a glaze and coat the pork. The skin should be sticky and yielding, not rubbery — this is the technical benchmark.
Awamori (泡盛) is Okinawa's indigenous distilled spirit — made from long-grain Thai rice (not Japanese short-grain) and distilled to 25–43% ABV. It is the oldest distilled spirit in Japan with a history dating to the 15th century. Aged awamori (kūsu, 古酒) develops complexity comparable to aged whisky. The best rafute uses aged awamori, which adds caramel and vanilla-adjacent complexity to the braise. Rafute is traditionally served at Okinawan family gatherings and the dish improves significantly when reheated the next day.
Not blanching first — the excess fat makes the braising liquid greasy. Using sake instead of awamori — the flavour difference is significant; awamori's higher ABV and different aromatic profile are distinctive. Simmering too vigorously — the pork should barely tremble in the liquid. Not reducing the glaze at the end — the glossy caramelised finish is essential.
