Oyster leaves are a culinary magic trick. These smooth grey-green leaves look like any salad green, but actually have a juicy texture and briny, oyster-like flavor.
Oyster leaf has become popular in cutting edge fine dining restaurants as a way to surprise and delight diners. For a long time this plant was only available wild foraged (originally from the coast of Scotland), but rising restaurant demand has induced farmers to start cultivating it.
