Red Currant Jelly
Select fine, large, red currants, pick from the stalks and place in a preserving-pan over a moderate fire; break the currants with a wooden spoon until the juice is extracted; then strain through a jelly-bag, and to every breakfast cupful of juice add half a pound of sugar. Put both juice and sugar into a preserving-pan, set it on the stove, and let it come gradually to a boil. Then boil for ten minutes, and when a little cool, put into glasses or moulds, and when quite cold, turn out.
A straightforward high-pectin jelly that needs almost nothing but fruit, sugar and attention to the set. Two things in the original wording will trip a modern cook: the cup measure and the ten-minute boil.
- Breakfast cupfulAn imprecise measure even in 1900: a breakfast cup was simply a large cup, usually reckoned at somewhere around 8 to 10 fluid ounces, and usage varied from writer to writer. Treat it as 1 cup (240 ml) of juice to 8 oz (about 1 generous cup) of sugar and you are within the intended range.
- Moderate fireOn a modern burner this is medium-low. The currants are heated dry, with no added water, only until the skins burst and the juice runs; too hot and the pulp scorches before it gives anything up.
- Do not squeeze the bagLet the jelly bag drip on its own, however slowly. Pressing or wringing forces pulp and fine sediment through and the finished jelly will be cloudy rather than clear.
- The ten minutes is a guide, not a ruleRed currants are among the most pectin- and acid-rich fruits there is, so a short boil genuinely works — but stove output varies. Cook to 220F (104C) on a thermometer, or until a spoonful sheets and wrinkles on a chilled plate. Overboiling gives a tough, syrupy jelly that tastes of caramel.
- SkimLift the foam off just before potting. Stirred back in, it leaves the surface hazy and full of bubbles.
- Moulds versus jars"Turn out" means this was set firm enough to unmould and serve as a shape on a dish, alongside game or lamb. A jelly that firm needs a full set; if you want a spreadable consistency, pot it in jars and leave it there.
- Yield and keepingYields vary with the fruit, but expect roughly a pint of juice from 2 lb of currants, so a few pounds of fruit will fill two or three half-pint jars. The recipe has no sealing step: refrigerate and use within a few weeks, or process filled jars by a current water-bath method if you want them shelf-stable.
Red currants (Ribes rubrum) are a northern European fruit, long valued less for eating out of hand than for the fact that their juice sets almost by itself — the acid and pectin are high enough that jelly-making needs no additive and barely any cooking. That reliability made red currant jelly a staple of the professional larder rather than just the preserving cupboard: it glazes fruit tarts, sweetens and colours Cumberland sauce, thickens the pan gravy for venison, and goes to table in its own right with lamb and game. Its scarcity in American markets today has a specific cause: currants and gooseberries host white pine blister rust, and in the early twentieth century a number of states restricted or banned their cultivation to protect the timber industry, with some of those rules surviving for decades. When Oscar wrote, the fruit was still ordinary; a generation later it was not.
