Method
- Dissolve the 25g salt in the 240ml water. Pour into the flour and mix with chopsticks until shaggy. Knead with the heel of your hand for ten minutes — the dough will go from sticky and rough to smooth and very firm.
- Place the dough in a plastic bag and stamp on it with bare feet, wrapped in cloth, for five minutes. This is the traditional Sanuki technique; rolling and folding by hand also works. Rest one hour, covered.
- Roll the rested dough into a 5mm sheet. Dust heavily with flour, fold like an accordion, and slice into 5mm-wide noodles. Shake apart — the strands should be square in cross-section, not round.
- Cold-soak kombu and iriko in 1.5L water for at least 30 minutes (overnight is better). Heat slowly, pulling the kombu out just before boiling. Simmer the iriko for ten minutes, then strain. This is the Sanuki dashi.
- Season the dashi with soy, mirin and salt. Taste — the broth should be light and clean, with a deep saltwater-fish bottom note from the iriko. It should not taste of soy first.
- Boil the udon in a large pot of unsalted water — they need room to move. Cook 11 minutes for fresh, the noodles should be opaque-white through. Rinse briefly under cold water to remove starch, then warm in the dashi for ten seconds. Serve in deep bowls with garnishes on the side.

Cultural Note
Sanuki udon is the udon — Kagawa Prefecture on Shikoku Island has more udon shops per capita than anywhere on earth, and 'Sanuki' is the old name for the region. The defining feature is the koshi: the firm, springy bite that comes from high-protein flour, salt-water hydration, and the foot-stamping kneading method. A typical Kagawa breakfast is kake udon for 300 yen, eaten standing at a counter while the next batch boils.
