Lemon Juice, Salt, and Cayenne
Take the eel (or whitings or flounders), cut them up into pieces, and put them in a stewpan with the stock, parsley, carrot, cleaned and cut up, celery, thyme, mace, peppercorns, anchovies, and salt; let it boil up, skim it well, and let it cook for one hour, then strain it off. Put two ounces of butter and two ounces of flour into a stewpan, mix them well together, and pour in the fishstock: stir it well, and boil for ten minutes; then strain it through a hair-sieve. Blanch and beard the oysters, strain them, and save the liquor.
Put the soup on the fire and make it boil, then draw it off the fire; mix the cream and yolks of eggs together, a few drops of lemon-juice, and a little cayenne; strain this into the soup and stir it over the fire until the eggs are cooked, taking care it does not boil, or it will curdle. Just before serving, put in the oysters and the oyster liquor.
This is a Victorian fish velouté finished with a liaison of egg yolk and cream, with oysters added at the last moment. The printed page carries only the method — the quantities lived in a separate ingredient list — so treat the amounts below as reconstruction rather than transcription.
- Missing quantitiesOnly the butter and flour (2 oz each) are specified. For that quantity of roux, work on 2 pints of fish stock, 1 to 1 1/2 lb of eel or white fish, about 1/4 pint cream, 2 to 3 egg yolks and 12 to 18 oysters. These are proportions consistent with the period, not figures from the book.
- The hinge: never let the liaison boilOnce cream and yolks go in, hold the soup between 165F and 180F and stir until it thickens to coat a spoon. Above about 185F the yolk proteins seize and the soup breaks into curds that cannot be brought back.
- Blanch and beard the oysters"Blanch" here means a brief dip in their own liquor until the frills just tighten — well under a minute. "Beard" means trimming off the tough dark gill fringe. Adding them at the end, off the boil, is deliberate: a minute too long and they turn to erasers.
- Strain the oyster liquorOyster liquor carries shell grit. Pour it through muslin or a fine sieve before it goes into the soup, and add it at the very end — it is salty, and it will tip the seasoning if added before you have tasted.
- MaceBlade mace, the lacy outer coat of nutmeg, not ground mace. One blade is enough for two pints; it gives a warm note quite different from nutmeg's sweetness. Ground nutmeg at the tip of a knife is the nearest substitute.
- AnchoviesProbably salted anchovies from the barrel, which dissolve into the stock; bottled anchovy essence was equally common in period kitchens. Two or three oil-packed fillets, or a teaspoon of anchovy paste, do the same work. Add the salt after the anchovies have melted in.
- Hair-sieveA horsehair sieve. Hair sieves were the standard tool for fine straining before cheap fine wire mesh, and were favoured for acidic or eggy mixtures that metal could taint. A fine nylon or stainless sieve, or a chinois, is the modern equivalent.
- EelWhole eel is now scarce and European eel is a species of conservation concern; the recipe's own alternatives — whiting or flounder — are the sensible choice. Use heads, frames and trimmings for body, and keep the stock at a bare simmer for the hour so it stays clear.
- YieldAbout six generous soup plates. It does not reheat: the egg liaison will curdle on a second boil, so make only what will be served.
Soups of this kind — a fish stock thickened with roux, refined through a sieve and enriched at the last with yolks and cream — were the backbone of the fish course in late-Victorian and Edwardian service, sitting somewhere between a French velouté de poisson and the older English oyster soup. Eel was the natural base for a cook working in Britain then: it was cheap, widely available at market, and its gelatinous flesh gave a body that lean flatfish could not — which may be part of why whiting and flounder appear as substitutes rather than first choices, though that is inference rather than anything the book states. Oysters, likewise, were still a commonplace ingredient rather than a luxury for much of the nineteenth century, used by the dozen to season and garnish, although beds were failing and prices climbing from the 1860s and 1870s onward; the instruction to save every drop of their liquor reflects a kitchen in which the shell water was understood as the most concentrated flavour in the dish. The awkward title of this page is most likely an artefact of the book's layout, in which ingredients were printed as a separate column and the last line of that list appears to have been carried over as a heading.
