To Pickle Rock
Put Cook a rock-fish (cut in pieces) in water enough to cover. in a handful of salt, a little white pepper, one table-spoon of allspice, a few cloves and mace. When fish is near done, add a quart of vinegar. In putting away, cover with liquor. - Mrs. J. S. W.
This is a preserving recipe rather than a supper dish, and the preserving part is where it fails. The notes below explain what the text says and why the method should not be followed.
- The text is scrambledThe opening line has been transposed in the original setting; it should read something like "Cook a rock-fish (cut in pieces) in water enough to cover. Put in a handful of salt..." The garbling is in the source and is reproduced as printed.
- What a rock isIn Southern and Chesapeake usage, rock or rockfish means striped bass, Morone saxatilis. It is not the Pacific rockfish sold under that name on the West Coast today. Striped bass is a regulated species, with size and season limits in many jurisdictions.
- No measured acidityA quart of vinegar is added to an unspecified volume of cooking water already loaded with salt and fish juices. The finished liquor could land anywhere from sharply acidic to barely acidic at all. Safe pickled fish depends on a known acid concentration, and nothing here provides one.
- The storage instruction is the problem"In putting away, cover with liquor" means an ambient-temperature crock or jar. Cooked fish held under a weakly acidic brine at room temperature is a textbook substrate for Clostridium botulinum, which grows without oxygen and produces toxin that no amount of tasting will reveal.
- Salt is not quantified eitherA handful of salt is not a curing measurement. Cures that actually inhibit bacterial growth are calculated as a percentage of the weight of fish and brine, and this recipe gives neither weight.
- No processing stepThere is no boiling water bath, no pressure processing, no sealing procedure. Whatever kept such preparations edible -- a cool larder, strong vinegar, relatively quick consumption -- the printed recipe never states it.
- If you want pickled fishUse a current tested recipe from a food-preservation authority, which will specify vinegar strength, salt weight, refrigeration and a holding time.
Rockfish, the Chesapeake and Southern name for striped bass, was one of the great abundant fishes of the Atlantic seaboard, netted in quantity in spring runs and often arriving at a household in more weight than could be eaten fresh. Pickling in a spiced vinegar liquor was one of the standard answers, alongside salting and smoking, and the spice list here, allspice, cloves and mace, is the same warm-sweet combination used for pickled oysters, spiced beef and mincemeat in the same period. The Dixie Cook Book, an edited commercial compilation as much as a community collection, prints such receipts with initials attached and no attempt at standard measures, so the quantities reflect one woman's kitchen habits rather than any tested procedure. The confidence of "in putting away, cover with liquor" belongs to a world of cold cellars, quick turnover and a tolerance for risk that modern food safety does not share.
