Liver Soup, Brown
Put into a saucepan a slice of bacon, an onion, some cloves and black peppercorns, a pound of lean minced beef, and an ounce of grated carrot. Fry for a minute, then pour in water to cover, and simmer until the moisture has nearly dried up. Then pour in three pints of stock made from bones, and cook gently for an hour or two. Press the meat, etc., from time to time, then strain the soup off, and put to it six ounces of calf's liver that has been fried and pounded and seasoned with salt, black pepper, nutmeg, and powdered herbs. Add a little brown roux, boil the whole up, and serve with strips from a French roll dipped in hot butter and crisped in the oven.
A two-stage soup: a browned meat essence is built and strained, then enriched at the last with pounded fried liver. Most of what can go wrong happens in that last five minutes.
- The hinge: liver goes in off the boilThe hinge: the liver goes in at the very end -- The pounded liver acts as a thickener and flavouring rather than something to be cooked at length. The recipe says to boil the whole up once it is in, so bring it barely to a boil and serve; prolonged boiling tends to make liver purée grainy and can give the soup a chalky edge.
- Pound it properly"Fried and pounded" means fried until just firm and no longer pink at the centre, then worked to a smooth paste in a mortar. A food processor does it faster; push the paste through a sieve afterwards if you want the velvety texture the original assumes.
- Three pints of stockImperial pints of 20 fl oz, so about 60 fl oz — roughly 7 US cups or 1.7 litres. It reduces over the hour or two of simmering and is then strained; the recipe gives no yield.
- The first stage is a fond, not a soupFrying the bacon, beef, onion and carrot, then adding water and letting it simmer almost dry, is the classic method for drawing out juices and letting them caramelise on the pan bottom. That brown film is the whole point; the stock added afterwards dissolves it.
- "Fry for a minute"Optimistic. Give it long enough for the bacon fat to render and the meat and onion to take colour — five to eight minutes over decent heat.
- Brown rouxEqual weights butter and flour cooked to the colour of a hazelnut shell. An ounce of each will lightly body three pints; the soup should coat a spoon, not stand up in it. The recipe adds it after the liver, immediately before boiling up.
- Powdered herbsPowdered dried herbs were a common Victorian storecupboard item; such blends typically drew on herbs like thyme, marjoram, savory and bay, ground to dust. Half a teaspoon of dried mixed herbs, crushed fine, does the same job.
- The garnishA French roll here is most likely a small crusty white roll rather than a baguette. Cut into finger-width strips, tossed in melted butter and crisped until dry through — the recipe gives no temperature, but around 375F for eight to ten minutes works.
Brown liver soup belongs to the family of nineteenth-century "essence" soups, in which a small quantity of meat is sacrificed entirely to flavour a larger quantity of stock and is then thrown away — a practice that reads as extravagant now but was standard in kitchens with a joint's worth of trimmings and a stockpot always on the range. The technique of frying, moistening, reducing to a glaze and moistening again is one that English cookery books took up from French professional practice through the century. Liver as a thickener is older still: medieval and early modern European sauces sometimes leaned on pounded liver where a later cook would reach for flour, though bread, almonds and egg yolks served the same purpose, and the survival of the method here, alongside a roux, shows the recipe straddling two traditions. Calf's liver was the expensive choice, milder and finer-grained than ox.
