I am almost ashamed to admit that samphire can be bought locally in Waitrose. But it is getting a bit stringy now - I guess it is getting to the end of its season. And I would be careful about picking it locally along the river because it was getting very scarce when I last looked and I would hate for it to be wiped out altogether. Unfortunatley the uninitiated tended to pull it out by the root rather than just cutting off the tips so that it could grow again. And I guess river pollution hasn't helped.
