Gooseberry Biscuits
Gather the fruit when full grown, but not ripe; put them into a jar and set them to boil in a kettle of water till soft, then rub through a sieve. To every pound of pulp allow a pound of loaf sugar; stir the mass over the fire until the sugar is dissolved, then pour it into shallow dishes to dry in the sun or in a cool oven. When it begins to candy it may be cut into any desired shapes. Turn them every day until they become dry and hard, and keep in tin boxes in a dry place.
This is a fruit paste confection rather than anything resembling a modern biscuit — closer to Turkish delight or quince membrillo in method. The whole point is slow, gentle drying, and rushing it is the one way to ruin the batch.
- The hinge: dry low and slow"a cool oven" in a range of this period is generally taken to mean somewhere around 200-250F; a modern oven at its lowest setting with the door propped ajar will do, as will a dehydrator on a low setting. Too much heat and the sugar colours and the pieces stay sticky instead of setting to a firm candy.
- Unripe fruit is deliberateFull-grown but green gooseberries carry the most pectin and acid, which is what makes the paste set. Ripe fruit gives a slack, syrupy mass that never firms up properly.
- "Put them into a jar" in a kettle of waterThis is a water bath, not direct heat — the jar sits in simmering water so the fruit stews in its own juice without scorching. A heatproof bowl over a pan of water does the same, or simply cook the berries in a heavy saucepan with a splash of water over low heat.
- Loaf sugarLoaf sugar was refined white sugar sold in a hard cone and broken up as needed. Ordinary granulated sugar is the direct equivalent; weigh it, since the pound-for-pound ratio to pulp is what preserves the paste.
- Rubbing through a sievePush the softened fruit through a fine sieve or use a food mill to leave skins and seeds behind. A blender will not do the job — it pulverises the seeds and the paste turns gritty.
- Cooking the sugar inStirring "until the sugar is dissolved" is the minimum; a few minutes more of gentle cooking drives off water and shortens drying time considerably. Stir constantly, as the mixture catches easily once thick.
- Shallow dishesLine a rimmed baking sheet with parchment or a silicone mat and spread the paste about a third of an inch thick. Turning the pieces daily, as instructed, exposes both faces to the air and is still necessary.
- Yield and keepingHow many pieces you get depends entirely on how thickly the paste is spread and how small it is cut, neither of which the recipe specifies. A tin lined with parchment keeps them separate; they will hold for months in a dry place, but humidity makes them weep.
Sugared fruit pastes of this kind were among the oldest forms of preserving in English kitchens, and are generally traced back to the medieval and Tudor "quiddany" and "marmalade" — stiff, sliceable sweetmeats served at the end of a meal long before jam in jars became commonplace. The word biscuit is used here in its older, looser sense of something hard and dried rather than a leavened batter — the name is often said to derive from bis coctus, twice-cooked — which is why the entry sits oddly to modern eyes. Gooseberries were a British obsession in the nineteenth century, cultivated competitively by clubs of working-class growers in Lancashire and the Midlands who chased ever-larger fruit, and a household with bushes had far more green berries than it could use for pies and fools. Drying the paste in the sun points back to a pre-oven tradition; by the time Cassell's was compiled, the cooling range after the day's baking may well have served the same purpose.
