In a large bowl of cold water, wash and rub together approximately three cups of periwinkles, each about one inch in diameter. Lift the periwinkles from the water and put them in a medium saucepan, preferably stainless steel.
Add the olive oil, Tabasco, and wine to the periwinkles and bring to a hard boil. Cover and boil for 2 to 3 minutes, removing the lid and stirring them once or twice while they cook. Transfer to a bowl, let cool to warm, and enjoy.
Straight pins can be used to remove the snails from their shells. (Pépin notes: “At our house, we stick several pins into a wine cork and pull them out as needed at the table.”) The operculum should be removed before sticking a pin into the shell opening and extracting the flavorful meat.
Serve with an apéritif; Jacques Pépin prefers Campari and soda, or white wine.
