What is it?

Koori soba, also called shimi soba, forms boiled buckwheat noodles into small nests, freezes them outdoors at night and thaws and dries them in daytime sun repeatedly until lightweight and shelf-stable.

History and local context

The cold-climate preservation food was once served as a treat to guests, then declined before local soba makers revived it. It now appears as a distinctive Nagano souvenir as well as a demonstration of natural freeze-drying.

How to enjoy it

Rehydrate a bundle by shaking it in a small strainer inside hot vegetable broth, then eat as soon as the strands soften. Follow product timing so the fragile noodles do not dissolve, and store the dry nests away from moisture.

Availability varies by maker, season, and destination.
