Glasswort (Sebalnamul)
Salicornia europaea
Sebalnamul gets its name from its appearance: se means thin or three, and bal means legs or branches — describing how each tiny plant branches into three delicate, finger-like stems. This glasswort grows naturally on the tidal flats along Korea's western and southern coasts. For coastal communities, sebalnamul was a free, abundant spring green gathered by hand from salt marshes during low tide. Its natural saltiness meant that no seasoning salt was needed. The same plant is known as samphire in British cuisine and sea beans in American coastal cooking, making it one of the few Korean ingredients with direct Western equivalents.
New to Glasswort (Sebalnamul)?
Is this edible?
Yes! And you may already know it by another name — sea beans or samphire. It's the same plant (Salicornia) that's trendy in Western fine dining.
What does it taste like?
Imagine a tiny, crunchy vegetable that tastes naturally salty — like it absorbed the ocean. Crisp, clean, and briny.
Where to buy
In the US, look for sea beans or samphire at Whole Foods, specialty grocers, or coastal farmers' markets. At Korean groceries, look for sebalnamul.
How to prepare
The easiest Korean vegetable to prep: just wash and eat raw! For Korean-style muchim: toss with a little vinegar, sesame oil, and minced garlic. No salt needed.
Pro tip: Sebalnamul is naturally so salty that it can replace salt in dishes. Try chopping it finely and mixing into rice or tofu dishes for a natural, mineral-rich salt boost.

Processing Methods (법제)
Sebalnamul is best enjoyed raw to preserve its unique crunchy, succulent texture and natural saltiness.
A 5-10 second blanch slightly softens the stems and reduces saltiness if too intense. Do not over-blanch.

Mineral supplementation
Eat raw sebalnamul as a banchan or snack. Its natural mineral content is absorbed more efficiently than synthetic mineral supplements.
