Defrosting and shelling:
Immerse the Obsiblue in cold water for a few minutes, then rinse them and drain thoroughly. Once thawed, hold the head of the Obsiblue with one hand and the body with the other hand. Pull gently to detach the head. Flip the Obsiblue to remove the shell. Dry gently.
Tip: It is possible to keep the raw shelled Obsiblue in the refrigerator for 24 hours. To do this, arrange them on a plate and cover with cling film.
