Milk Jelly
Put into a saucepan one pint of milk, half an ounce of sheet gelatine, one and a half ounces of castor sugar, and a strip of lemon-rind. Heat gently until the gelatine is dissolved, then strain. Let this cool in a basin until it begins to set, then place it in a mould. When firm turn out and serve. Probable cost, 6d.
A plain moulded milk jelly of the sort Cassell's treats as a foundation exercise rather than a showpiece. Almost everything hangs on the gelatine, which is the one ingredient that has genuinely changed.
- Gelatine strengthHalf an ounce is about 14 g, which by modern standards is a stiff set for a pint of milk. Modern gelatine is generally reckoned stronger and more consistent than the Victorian product, though nineteenth-century sheet gelatine was not graded by any standard measure, so the comparison is approximate. Around 9-10 g of leaf gelatine gives a set that trembles when turned out rather than one that squeaks under the spoon.
- Leaf versus powderModern leaf gelatine should be soaked in cold water until floppy, squeezed out, and stirred into the warm milk; the soaking water is discarded. Powdered gelatine of the same weight works, sprinkled over a few spoonfuls of cold milk and left to swell before it goes in.
- The pintAn imperial pint is 20 fl oz, about 570 ml, not the American 16 oz. Using a US pint with the full weight of gelatine will make the jelly noticeably firmer still.
- Heat gently means gentlyThe milk should reach no more than a steaming 60–70C. Boiling scalds the milk, throws a skin, and gains nothing — gelatine dissolves well below simmering point and prolonged high heat weakens its set.
- Castor sugarSuperfine or baker's sugar; ordinary granulated dissolves perfectly well here since the mixture is heated. One and a half ounces is about 40 g, which is restrained — taste the warm milk and adjust before straining.
- Lemon-rindPare it with a peeler so no white pith goes in, and leave it in the milk while it heats and again while it cools slightly, then strain it out. It is the only flavouring in the dish, so a generous strip is worth having.
- Yield and turning outA pint fills a 600 ml mould; the recipe gives no number of servings, but it would stretch to about four small portions. Rinse the mould in cold water before filling, and to unmould dip it briefly in hot water to the rim, then invert onto a wetted plate so the jelly can be slid into place.
Milk jellies sit in the plainest corner of the Victorian sweet repertoire: cheap, mild, easy to digest, and for that reason recommended constantly for children and invalids as well as for the family table. The costing of sixpence is the point of the entry as much as the method — Cassell's habitually priced its dishes so a housekeeper could budget — and it marks this as an everyday pudding rather than a show mould. Commercial sheet gelatine, sold in thin translucent leaves, was by the late nineteenth century increasingly displacing the laborious business of boiling calves' feet for their jelly, though calf's-foot recipes persisted in cookery books of exactly this period, and it is that change that put moulded creams and jellies within reach of ordinary kitchens. The same base, enriched with cream, flavoured with coffee or chocolate, or set in layers, lies behind a number of the moulded sweets that follow it in books of this period.
