Preparation / Directions:
Here's an illustrative recipe from "Tahitian Cooking".
The turbot snails are available around here--in pet stores for something like eight bucks a pop! They might be available in a Chinese seafood market for a reasonable price. I'll check the next time I'm up that way.
The snail of the ma'oa may be extracted from the shell either by breaking the shells with a hammer or by boiling them for a few minutes if you wish to keep the shells intact. Wash the snails and remove the pocket of black matter.
In the case of the pahua, a bivalve, the muscle adhering to the shell should be severed, the animal extracted from the shell, and the black matter removed. Soak in fresh water for a few hours.
Mix with the taioro, then add the chopped onions and garlic plus seasoning. Serve at room temperature.
