Lamsoor is the Zeeland name for the sea aster. The lamsoor consists of lance-shaped mild, salty leaves that grow in rosettes. Lamsoor grows on a salty soil in, for example, coastal areas and is less salty than samphire. The crunchy leaf of the lamsoor is edible raw, but best when cooked al dente. In combination with fish, shellfish, or crustaceans, it is an ideal vegetable dish.
