The tender young leaves (strigoli) of the bladder campion (Silene vulgaris), are eaten in Spain, Greece, Umbria and parts of Lazio and Romagna. Foraged in the spring time (along with wild asparagus), their taste resembles tart rocket, a bit like sorrel; they are used in pasta sauces. They sometimes appear in greengrocers as well as on seasonal menus. You may also see strigoli di fosso, or 'from the ditch' which is where they usually grow.
More commonly, strigoli are a homemade pasta shape that resembles fat worms, sometimes spelled stridoli.
