About Laitue de mer (Ulva sp.)

Laitue de mer, or sea lettuce, refers to edible green marine algae in the genus Ulva. The thin, flexible fronds are usually bright green and resemble delicate, ruffled leaves; species and growing conditions affect their size and form.

It is sold fresh, dried, or rehydrated, and may be eaten as a vegetable or used in soups, salads and seasonings. Its flavour is briny and mildly vegetal, while dried material is papery and concentrated. Fresh, dried and rehydrated forms differ substantially in water content and texture.
