Saw a small, weathered sign at the side of the road.
A restaurant, it turns out: Pickled Wrinkle.
While that particular location is long gone, not so over at Birch Harbor, near Acadia National Park.
“Wrinkle,” as I’ve learned, is a diminutive of “periwinkle,” which are commercially harvested around here. In the old days, pickling them was perfect for packing and shipping. And they are an invasive species, FYI.
As for today, you can look up the recipes yourself.
So much for local flavor. Or maybe French.
