At the market, yesterday morning, I bought three
green ormers. The fishmonger had four out on ice on his stall; I told him that there would be three of us for supper so I'd want either three or six, but he didn't have another two so I came away with three and he was left with just one lonely ormer.
This is, I think, the only time I've ever seen them for sale. The fishmonger told me that there are strict rules concerning the size, the season and the numbers that can be harvested, so while they're not excessively expensive they are still somewhat rare.
