About Sea aster

Sea aster, also called zulte in Dutch, is a coastal leafy plant used as a vegetable. Its leaves are green and fleshy, with a crisp texture and a distinctly savoury, salty flavour associated with its seaside growing conditions.

The leaves are eaten raw in some preparations or cooked briefly as a green vegetable. They are commonly sold fresh in bunches or as trimmed leaves, and may also be preserved. Preparation and flavour can vary with the growing environment and whether the leaves are young or mature.
