Harusame Glass Noodles Japanese Applications
Japan — harusame introduced from China, adapted into Japanese cuisine
Harusame (春雨, spring rain) are Japan's glass noodles — thin, translucent threads made from potato starch, mung bean starch, or sweet potato starch. The name 'spring rain' reflects their appearance when cooked: delicate, light, and translucent like gentle spring rainfall. Unlike Chinese glass noodles (which can be similar), Japanese harusame are used in specific traditional contexts: salads (harusame salad with vinegar-sesame dressing), hot pot, and as a nimono ingredient absorbing flavors. Harusame expand significantly when hydrated and absorb surrounding flavors efficiently. They require only brief soaking in hot water rather than boiling.
