Phantom somen
Somen are very thin wheat noodles, usually eaten cold in summer. Nankan somen is one of the few in Japan still kneaded and stretched entirely by hand, without a single machine. Output is small, so people call it maboroshi no somen, phantom somen. It slips down smoothly and has a firm, springy bite, and orders come in from all over Japan.
A winter craft
Nankan town in Kumamoto sits in a basin ringed by hills, with cold, dry winters that are perfect for drying noodles. Good wheat and salt came from nearby, so farmers made somen as winter work. They have kept the all-hand method since the Edo period.
Good to know
- Eat somen cold with a dipping sauce, ginger and spring onion, or hot in winter as nyumen.
- Nankan is near the Kyushu Expressway, under an hour north of Kumamoto city.
