What is it?
Urui is a spring mountain vegetable (sansai). It is also commonly known as Hostas, Ginbo, or Oobagiboshi. Although it is a wild vegetable, most of the urui found in Japanese supermarkets are now grown in greenhouses. They have a long white stem and small, soft yellow-green leaves, which are all edible.
How can it be eaten?
The vegetable has a simple taste similar to asparagus. Urui can be eaten raw in salads, boiled, stir-fried or made into tempura. Upon cooking, urui can take on a slimy texture.
