Peaches, Bottled
Pare, halve, and stone the peaches. Place the halves in perfectly dry wide-mouthed bottles, and cover them entirely with a thick syrup, made by boiling a pound of loaf sugar in three-quarters of a pint of water until the sugar is dissolved. Wrap a wisp of hay round them to prevent their knocking against each other, and place them side by side in a deep stewpan, with cold water up to their necks. Bring the water to boiling point, and let the peaches boil gently for a quarter of an hour, then lift the saucepan from the fire, and do not remove the bottles until the water is almost cold. Cork the bottles and seal the corks, and store in a cool dry place. Probable cost of peaches, 2d. to 6d. each.
This is Victorian fruit bottling, and the method it describes has been superseded for good reason. The notes below explain the vocabulary and then why the preserving procedure itself is the problem.
- The seal is made after processing, not duringThe bottles are corked only once the water bath has cooled, which means the cooled, partly open headspace is exposed to room air before closing. No vacuum seal forms, and nothing verifies that a seal has held. Modern tested procedures close the jar before processing so that cooling draws the lid down and creates the vacuum.
- No headspace, no verified process timeNo stated headspace, no jar-size or altitude adjustment -- Filling the bottles so the fruit is "entirely covered" with syrup leaves little guidance on expansion space. The quarter of an hour is timed from the moment the water reaches boiling point, but tested peach processes also vary the time with jar size and altitude, which this does not.
- Corks and sealing wax are not a preserving closureCorks and sealing are not a preserving closure -- The recipe says only to cork the bottles and seal the corks, without naming the sealing medium; corks sealed over with wax or resin were a common period closure, but they flex, wick and admit air over months of storage. Spoilage in a corked bottle of syruped fruit shows up as mould, fermentation and yeasty pressure rather than anything dramatic, but the batch is lost and should not be tasted.
- What to do insteadPeaches are a high-acid fruit and bottle well, but follow a current tested water-bath canning recipe with proper two-piece lids, stated headspace and altitude-adjusted timings. Do not adapt the instructions above.
- Loaf sugarSugar sold in a hard cone, broken up with nippers; plain granulated white sugar is the direct equivalent by weight.
- The syrup measureThree-quarters of an imperial pint is 15 fl oz, about 13/4 US cups. A pound of sugar to that quantity of water is a heavy syrup by any standard.
- Stewpan and wisp of hayA stewpan is a straight-sided saucepan, here deep enough to stand bottles upright with water up to their necks. The hay is padding to stop the glass knocking; a modern canner uses a wire rack and jar dividers for the same purpose.
- The costing"2d. to 6d. each" is twopence to sixpence per peach in pre-decimal currency, a reminder that peaches were a glasshouse or imported luxury in most British households at the time.
Bottling fruit in syrup and heating it in a water bath descends from the work of Nicolas Appert, whose sealed-and-heated preserving method was published in France in 1810 and spread through British domestic manuals over the following decades. By the time Cassell's was compiling its dictionary, the technique was well established in the domestic literature for gluts of soft fruit, though the science lagged the method: cooks knew that heat and an airtight closure worked without knowing what they were killing, which is why period instructions vary so widely in time and temperature. Peaches themselves were not an everyday fruit in Britain then, being largely a walled-garden or glasshouse crop supplemented by imports, and the per-fruit costing given here rather than a price per pound may suggest they were bought singly. The wisp of hay is the most telling detail: purpose-made preserving jars with rubber rings and clamped lids existed by this date, yet the instruction assumes a kitchen improvising with whatever wide-mouthed bottles the household had accumulated.
