Potted shrimps - not to be confused with the American 'shrimp' which in the UK are known as prawns. These are a different species - tiny, fiddly to shell and very delicious. In France they are known as crevettes gris. Morecambe Bay in Lancashire is particularly known for brown shrimps and they are traditionally made into potted shrimps. They are also fished in The Wash in North Norfolk. Potted shrimps are made by briefly boiling the shrimps, shelling them, preserving in butter and sealed with butter. The butter is traditionally flavoured with nutmeg and a combination of other 'secret' spices.

Once cooked and cooled, the shrimps are graded as size one (the biggest), two or three. Ones are the favourites, easiest to peel, but “most are smaller,” admitted Worrall phlegmatically. Some of the shrimp will be sold whole to restaurants, but most are peeled.
This was once entirely done by hand, but now there are a couple of Dutch machines to deal with the smaller ones. Even these struggle to turn out half a dozen tiny peeled shrimp a second, and seem peculiarly ineffectual. Helen, a cheerful blonde, was checking them, as three quarters of the shrimp still need hand-stripping.
