On the plate

Crunchy and very salty, with an acid edge at the finish.

Avoid: Salting it while cooking: it already carries all the salt a dish needs.

It was used to make glass for centuries. The plant was burned for its soda-rich ash, which is where the name glasswort comes from, and Venetian glassmakers imported it by the boatload.
