To clean and cook sea snails: Boil the snails for approximately 20 minutes in a pot of water. This will remove the sand and grit trapped inside the shell and cook the snail meat.
In a saucepan, heat up the olive oil and saute the garlic and chopped chile pepper. Then add the snails. Add the wine and cook for a few minutes. Add salt, parsley and toss together well. Serve immediately.
* Cook's Note: Provide guests with thin wooden skewers or sturdy toothpicks so that they can easily pick the snails out of the shells.
