Fig Jelly
Slice the figs into the preserving kettle, covering bottom of kettle with cold water. Add slices of unpeeled lemon, one lemon to one and a half pints of uncooked figs. Place on back of stove to cook slowly an hour, when strain and boil for fifteen or twenty minutes (according to the state of the syrup or the weather), adding three-fourths quantity of sugar to that of the fruit.
A short, loosely worded formula that assumes you already know how jelly behaves. The main thing it does not tell you is that figs are among the poorest jelly fruits there are, which is exactly why the lemon is not optional.
- The hinge: figs will not set on their ownFigs are very low in both pectin and acid, so this mixture may never gel and will more likely finish as a thick syrup or soft preserve. The unpeeled lemon supplies the acid and the pectin from its pith and peel; keep the full ratio of one lemon per pint and a half of figs, or add commercial pectin and accept it as a modern jelly.
- "Back of the stove"On a coal range this was the coolest zone, used for long unattended simmering. Translate it as the lowest burner setting, barely bubbling, for the full hour so the fruit softens and gives up its juice without scorching.
- Measuring the figsA pint and a half of sliced uncooked figs works out somewhere between about a pound and a pound and a half, depending on how loosely the slices pack. Fig sizes vary enormously between fresh Black Mission, Brown Turkey and Kadota, so weigh rather than trusting the volume.
- The sugar ratio is ambiguous"Three-fourths quantity of sugar to that of the fruit" most plausibly means three parts sugar to four parts strained juice, measured by volume after straining. Measure the juice you actually get, then add three-quarters as much sugar; less sugar than that and the set becomes even less likely.
- StrainingPour the cooked fruit into a jelly bag or a colander lined with several layers of damp cheesecloth and let it drip. Squeezing gives more juice but a cloudy jelly, and fig pulp clouds badly.
- Judging the boilThe fifteen to twenty minutes, and the aside about the weather, are a nod to how humidity affects the finish. Use a thermometer instead: 220F at sea level, or the point at which the syrup sheets off a cold spoon in two joined drops.
- Preserving kettleThe recipe specifies nothing beyond the word. Preserving kettles of the period were often copper or brass, though enamelled and granite ware were also in use. Any wide, heavy non-reactive pan works; width matters more than depth because evaporation is what concentrates the syrup.
- Yield and keepingExpect roughly two to three half-pint jars. The recipe gives no sealing or processing instructions at all, so treat the result as a refrigerator jelly, good for about a month; for shelf-stable jars follow a current tested water-bath canning procedure.
Fig recipes cluster in American cookbooks of the late nineteenth and early twentieth centuries because the fruit was a Gulf Coast and California dooryard crop that arrived all at once and would not keep a day — figs are highly perishable, which is why historical fig entries tend to be preserves, jams, jellies or drying instructions rather than fresh dishes. The lemon here does double duty in a way the author never explains: nineteenth-century cooks learned by trial which fruits "jellied" and which did not, and quinces, currants, crab apples and citrus were the standard fixes long before pectin was isolated and sold as a packet, generally traced to the second decade of the twentieth century. Instructions like "according to the state of the syrup or the weather" belong to that same pre-instrument world, where a cook read the drip off a spoon and adjusted for a humid afternoon.
