What is Akagai?
Akagai is often used for Sushi, or Sashimi. The best season of ark shell is from Dec. to Feb. Real akagai is ark shell, and fake is Sarubougai (half-crenated ark). But both are sometimes called “Blood Clam” or “Red Clam”.
Ark shell has about 40 stripes on its shell, but Sarubougau has about 32 stripes. If you see a cheap akagai in conveyor-belt sushi, that is not real akagai. Real akagai is expensive.
Yuriage (fishing port in Miyagi) is famous for ark shell. Morning market is opened every Sunday there.
How to open the shell
This is my way I learned by sushi chief.
- Tap the center of the shell using by a grip of knife.
- Remove breaking shell pieces and cut off adductor muscles by index finger or shell knife, then open the shell.
- Separate strings(=Kaihimo)
- Cut and clean
- Rinse with vinegar water (about water 100cc + vinegar 1Tsp) for 2-3 seconds.
- Cut for sashimi
