Pickled Oysters
200 large oysters 1/2 pint (I cup) vinegar 1 pint (2 cups) white wine 4 teaspoonfuls salt 1 teaspoonful white pepper 1/4 teaspoonful powdered mace Strain the liquor from the oysters, add to it the above ingredients, then put into an earthenware jar and allow to boil up. Pour while boiling hot over the oysters, and let them stand for a quarter of an hour;
This is a nineteenth-century keeping pickle written for a world of cheap barrelled oysters, cold cellars and rapid turnover. The method leaves shellfish essentially raw in a brine of unmeasured acidity, and it cannot be reproduced safely as printed.
- The oysters never reach a safe temperatureBoiling liquid poured over a large quantity of cold shucked oysters (200 large oysters is on the order of a gallon) equilibrates almost immediately, well below any pasteurising temperature, and fifteen minutes of standing does nothing to change that. The oysters are, for food-safety purposes, raw.
- Vibrio is the specific riskRaw and undercooked oysters carry Vibrio parahaemolyticus and Vibrio vulnificus, the latter with a high fatality rate in people with liver disease or compromised immunity. Modern raw-oyster safety depends on harvest-water certification and unbroken cold chain, neither of which this recipe assumes.
- The acidity is not preserving-strengthHalf a pint of vinegar is diluted by a pint of wine plus the liquor drained from 200 oysters. The finished pH is unmeasured and almost certainly above 4.6, which is the line below which pickles resist Clostridium botulinum. A jar of low-acid shellfish held at room temperature is exactly the condition modern canning guidance is written to prevent.
- No storage instruction at allNo storage instruction survives in this text — The excerpt breaks off mid-sentence after fifteen minutes' standing, so no processing step, no sealing, no keeping time and no temperature appear here.
- The vesselThe "earthenware jar" doubles as the cooking vessel, since the pickle is boiled up in it; acidic liquid in old glazed ware also raises a lead-glaze question.
- Scale200 large oysters is a market quantity, on the order of a gallon shucked by usual commercial counts. It signals a recipe meant for a household that bought oysters by the hundred, not a modern batch.
- If you want pickled oystersUse a current, tested recipe with measured acidity and a stated refrigerated shelf life, from a source that specifies cooking the oysters through.
Pickled oysters were a cheap and common food along the Atlantic seaboard. Oysters were sold by the hundred and by the barrel, and pickling in vinegar and wine with mace and white pepper was one way of using a glut and of carrying shellfish inland. The spicing here — mace rather than clove or allspice — follows older English practice. Its appearance in a collection otherwise given over to casserole cookery suggests a pickle section inherited from earlier household manuals rather than written for the rest of the book.
