Some piscivorous gourmands think that oysters are not best when quite fresh from their beds, and that their flavour is too brackish and harsh, and is much ameliorated by giving them a feed.
To FEED[189-§] oysters.—Cover them with clean water, with a pint of salt to about two gallons (nothing else, no oatmeal, flour, nor any other trumpery); this will cleanse them from the mud and sand, &c. of the bed; after they have lain in it twelve hours, change it for fresh salt and water, and in twelve hours more they will be in prime order for the mouth, and remain so two or three days: at the time of high water you may see them open their shells, in expectation of receiving their usual food. This process of feeding oysters is only employed when a great many come up together.
The real Colchester, or Pyfleet barrelled oysters, that are packed at the beds, are better without being put in water: they are carefully and tightly packed, and must not be disturbed till wanted for table. These, in moderate weather, will keep good for a week or ten days.
If an oyster opens his mouth in the barrel, he dies immediately.
To preserve the lives of barrelled oysters, put a heavy weight on the wooden top of the barrel, which is to be placed on the surface of the oysters. This is to be effected by removing the first hoop; the staves will then spread and stand erect, making a wide opening for the head of the barrel to fall down closely on the remaining fish, keeping them close together.
Mem.—The oysters which are commonly sold as barrelled oysters, are merely the smallest natives, selected from the stock, and put into the tub when ordered; and, instead of being of superior quality, are often very inferior. To immature animals there is the same objection as to unripe vegetables.
Obs.—Common people are indifferent about the manner of opening oysters, and the time of eating them after they are opened; nothing, however, is more important in the enlightened eyes of the experienced oyster-eater.
Those who wish to enjoy this delicious restorative in its utmost perfection, must eat it the moment it is opened, with its own gravy in the under shell; if not eaten while absolutely alive, its flavour and spirit are lost.
The true lover of an oyster will have some regard for the feelings of his little favourite, and will never abandon it to the mercy of a bungling operator, but will open it himself, and contrive to detach the fish from the shell so dexterously, that the oyster is hardly conscious he has been ejected from his lodging, till he feels the teeth of the piscivorous gourmand tickling him to death.
N.B. Fish is less nutritious than flesh: as a proof, when the trainer of Newmarket wishes to waste a jockey, he is not allowed meat, nor even pudding, if fish can be had. The white kinds of fish, turbots, soles, whiting, cod, haddock, flounders, smelts, &c. are less nutritious than the oily, fat fish, such as eels, salmon, herrings, sprats, &c.: the latter, however, are more difficult to digest, and often disturb weak stomachs, so that they are obliged to call in the assistance of Cayenne, Cognac, &c.
