3. The Secret to Our Great Taste

 Because sea urchins begin to fall apart after being removed from their shells, a preservative called alum is used to maintain their shape.
Alum prevents shape collapse, but loses the original melting texture and leaves the particular astringent taste on the tongue.

 The sea urchins of this restaurant are additive-free, not using alum but instead preserved using an original processing method conceived through longtime research.
Therefore, you can have the original sea urchin flavor.

  • Original processing technique not using alum.
  • Served with exquisite timing for freshness and taste.
