Japanese Okinawa Soba Regional Noodle Culture

Ingredients

• For the broth
• 1 kg pork bones, blanched and rinsed
• 30 g katsuobushi (dried bonito flakes), added in final stage of simmering
• 2 litres cold water
• For the rafute (braised pork belly)
• 600 g skin-on pork belly, cut into thick slabs
• 100 ml awamori (Okinawan rice spirit)
• 60 ml shoyu (soy sauce)
• 30 g brown sugar
• For the noodles
• 400 g strong wheat flour, no buckwheat
• 5 g salt
• 200 ml kansui solution, commercial kansui or baked-soda lye water; gives alkaline firmness
• To serve
• 120 g kamaboko fish cake, sliced thick
• 60 g beni shoga (red pickled ginger)
• To serve (optional)
• 1 small bottle koregusu, chilli peppers steeped in awamori; for tableside heat

Method

1. 1
   Place the pork bones in cold water, bring to a vigorous boil, and blanch for five minutes. Drain and rinse each bone under cold running water, removing all grey matter and impurities. The bones should be clean and pale before proceeding.
2. 2
   Return the cleaned bones to a large pot with two litres of cold water. Bring slowly to a simmer, skimming the surface repeatedly. Maintain a gentle, not rolling, simmer for several hours. In the final thirty minutes, add the katsuobushi. Skim once more, then strain through a fine sieve, discarding solids. Leave a light golden fat sheen on the surface — do not degrease completely. The finished broth must be clear and pale gold, savoury on the tongue but distinctly lighter than mainland tonkotsu.
3. 3
   Place the skin-on pork belly slabs in a heavy pot with the awamori, shoyu, and brown sugar. Add just enough water to half-submerge the pork. Bring to a simmer, cover, and braise over low heat, turning the slabs periodically and basting with the liquor. This is where the dish lives or dies: the rafute must cook until the skin yields completely under gentle pressure and the flesh is entirely gelatinous — any residual toughness means undercooking, and the braise cannot be rushed. When a chopstick passes through the skin with no resistance and the braising liquid has reduced to a lacquered, dark glaze, the rafute is done.
4. 4
   Combine the wheat flour, salt, and kansui solution. Knead until a smooth, firm dough forms. Rest, then roll and cut into thick, round noodles. The dough should feel noticeably more elastic and slightly stiffer than a plain flour dough — the alkalinity is working.
5. 5
   Bring a large pot of unsalted water to a full boil. Cook the noodles until they are cooked through but retain a distinct, firm chew — they must not soften into mushiness. Drain immediately and divide between four deep bowls.
6. 6
   Reheat the broth to a brisk simmer and season with salt if required. Ladle generously over the noodles in each bowl. The broth should be pale and clear, with a faint sheen of pork fat visible on the surface.
7. 7
   Arrange slabs of rafute, thick-cut kamaboko, and a portion of beni shoga over each bowl. The ginger should sit apart from the pork so that its sharpness and acidity read as a distinct counterpoint. Serve immediately with koregusu alongside for tableside addition.
