JELLY FOR THE SICK (Invalid Cookery)
Care should be taken in making jelly for invalids to ascertain whether or not wine and lemon-juice are allowed before putting them into the stock. Generally speaking, any very decided flavour is objected to, and sugar should be sparingly used, as sweetness cloys a delicate appetite. As, however, the acid and sugar materially assist the clearing of the jelly, it would be well, when these cannot be admitted, to add the white and shell of another egg. In this case, therefore, three instead of two eggs should be put with every pint of stock. Change of diet is very desirable for invalids. A pleasing variety may be made by making the jelly savoury instead of sweet. This can be done by stewing with the feet an onion, a dozen peppercorns, and a blade of mace. If a pound of the shin of beef be added to this, a very nourishing jelly will be produced. Time, five or six hours to stew. Probable cost of feet, 9d. to 1s. each. Two feet will make a quart of jelly.
This is a variation entry rather than a standalone recipe: it assumes you already have calf's-foot jelly stock going, and tells you how to adapt it for a sick-room. The important part is the clarification arithmetic and the savoury version at the end.
- The hinge: eggs replace acidLemon juice and sugar both help a jelly clear, so when they are left out the recipe compensates with an extra egg white and shell — three eggs' worth of white and shell per pint of stock instead of two. Whisk them into the cold stock before heating, bring it up while whisking, then stop stirring and let the raft rise undisturbed.
- Calf's feetThe whole method rests on feet simmered for their gelatin; two feet to a quart of finished jelly. Feet are now a special order from a butcher or a halal/Caribbean market. Pig's trotters behave the same way and are far easier to find.
- Powdered gelatine as a substituteIf you are not making foot stock, a savoury beef jelly can be set with about 7 g of powdered gelatine (one standard sachet, roughly 2¼ teaspoons) per pint of well-reduced strained broth. It will not have the same body.
- TimingsFive to six hours of stewing is right for feet — the collagen needs that long to convert. Keep it at a bare tremble; a rolling boil emulsifies the fat into the stock and no amount of egg white will clear it afterwards.
- A blade of maceOne piece of the dried lacy covering of the nutmeg seed, about an inch long. A generous pinch of ground mace is the nearest equivalent.
- The pound of shinShin of beef is the shank — cheap, sinewy, and full of connective tissue, which is exactly why it was chosen. It adds meaty flavour and yet more gelatin.
- Cost and yield"9d. to 1s." is ninepence to one shilling each, a period price with no modern equivalent worth calculating. Yield is a quart from two feet, which is roughly eight small invalid portions in cups or moulds.
- StorageThe original assumes a cold larder and prompt use. Treat it as fresh meat stock: chill quickly, refrigerate, and eat within three days, or freeze the stock before setting.
"Invalid cookery" was a fixed department of Victorian household manuals, and calf's-foot jelly was its emblem — alongside beef tea, arrowroot and gruel — because gelatin was believed to be concentrated nourishment that a weak stomach could take without effort. Gelatin is in fact an incomplete protein, though nineteenth-century opinion on its nutritive value was contested rather than settled; the recipe adds a pound of shin "to produce a very nourishing jelly." What the entry captures well is the sick-room logic of the period: no decided flavours, sugar sparingly because "sweetness cloys a delicate appetite," and above all the instruction to "ascertain" whether wine and lemon are permitted before the cook begins. The savoury version, with onion, peppercorns and mace, is essentially a set consommé, and it points forward to the clear aspics that stayed on English tables after invalid jellies had fallen out of medical favour.
