About this ingredient
Very thin (1-1.3 mm) wheat noodle, traditionally hand-stretched and aged. Three principal Japanese GI-protected origins: Miwa Sōmen (Nara, 1,300+ year heritage), Ibonoito Sōmen (Hyogo), and Shimabara Sōmen (Nagasaki). Distinguished from udon by thinness and from cold soba by wheat composition. Heritage production involves multi-day stretching / aging cycles; mass-volume retail is increasingly machine-extruded. A summer specialty served cold with mentsuyu dipping sauce.
