This is an irregular feature - both in frequency and oddness - dedicated to a word I came across that I have never previously used.
samphire - n. an edible wild plant found in coastal regions of Britain. The plant has fleshy, aromatic leaves that have long been regarded as a delicacy, and it is sometimes used as a garnish in London restaurants.
A variant, called golden samphire, is found throughout coastal areas of Eurasia.
The plant is sometimes referred to as "sea asparagus." Here is a tasty-sounding recipe for blanched samphire.
