Geoduck
Once a geoduck biotoxin sample comes back sub-lethal, once may indulge in any extra samples. Highly recommend sub-lethal levels of PSP before consuming--PSP tends to take away from the enjoyment some.
Remove siphon from a fresh geoduck. Blanch siphon for 30 seconds and then run under cold water. Peel off skin from siphon and slice siphon in half lengthwise. Then, cut siphon into very thin slices; slices will resemble tiny potato chips. Serve cold and raw with a wasabe-soy sauce mix. Tell your friends how much geoduck goes for in Asia to encourage sampling.
