I remember we used to eat opihi all the time in Kauai. My uncle Jimmy would take us to the beach and while we body surfed and played on the beach, he would climb the jagged rocks and waves risking his life to pick opihi.
We couldn't wait to get home so that we could grill the opihi in the shell over a hot hibachi and just as they were done cooking, we would pour shoyu over the opihi and eat it right off the grill.
Now, opihi is not as easy to come by and is extremely expensive. If you are lucky enough, try this recipe or do like we did and just use shoyu or better yet, eat them raw...my favorite way to eat opihi! Odelay...I'm still waiting for Fedex to deliver my opihi!!
2-3 lbs Opihi in shell
1 cup vinegar
1 cup water
1 tablespoon chopped garlic
1 teaspoon Hawaiian sea salt
Hawaiian Chili Pepper (to taste)
4 Tablespoons Butter
4 Tablespoons Aloha shoyu
Put opihi in a bowl or large ziplock bag. Add vinegar, water, garlic, salt, chili pepper. Marinate for 10-15 minutes before grilling.
In a small dish, melt butter, add shoyu and mix well. While grilling drizzle butter-shoyu mixture on opihi just as it starts to separate from the shell.
