This recipe for black sauce was popular all over Europe in the Middle Ages with many variations and alternative names like sauce infernal. They all use fried and ground livers as a base. In England it was served up with roast meat; capon in this case was used as were various game birds. Other countries used other additional flurries such as Parma ham, dried ceps, onions or garlic and spread it on toast or bread.

The recipe comes from a manuscript with the rather clinical name Ashmole MS. 1430, dating unsurprisingly from 1430. To put the year in context, Henry VI of the House of Lancaster is on the Throne; the political bubblings are beginning that led eventually to the War of the Roses around 20 years later. The original hand-scribed pages are kept in the British Museum, but the manuscript did appear in print along with some other 15th century cook books in the late 19th century.

Jane doesn’t give the original recipe that she bases hers on, but I did find it online. It is written in Middle English and takes a little deciphering:

Black sauce for capouns y-rostyde.—Take þe Lyuer of̘ capouns, and roste hit wel; take anyse, and grynde parysgingere, and canel, and a litil cruste of̘ brede, and grynde hit̘ weƚƚ aƚƚ to-gedre; tempre hit up wiþ verious, and þe grece of the capon, þanne boile it̘ and serue forþe.

I translate it as:

Take the livers of capons, and roast them well; take aniseed, ground ginger, and cinnamon, and a little crust of bread, and grind it well all together; temper it up with verjuice and the fat of the capon, then boil and serve forth.

Going back even further in time to the very first known practical cook book – Forme of Cury – written around 1390 contains a recipe for mallard in black sauce.

I made it to go with roast chicken rather than roast capon and it is best made whilst it is resting so you can skim off the fat from the roasting tin and use it to fry the livers.

Pass a beady eye over a pound of chicken livers, making sure that there are no big gristly bits or little green bile ducts left on them. Heat some chicken fat in a frying pan and add the chicken livers. Make sure that the heat is really high so that the livers brown nicely whilst keeping the insides moist and pink. This should take about 4 minutes in all – though it might be worth poking one of the biggest livers with a slenderly-pointed knife to check that the liver is not still raw. Medium rare is good, but anything less than that could be risky, there are several cases every year of Campylobacter brought about by eating undercooked chicken livers.

While the livers are frying, demolish a slice of bread, crusts removed, in a food processor; or if you want to keep it old school you can grate it.  Tip in the livers and whizz again – old-schoolers can pass them through a sieve or mincer. Season with the spices: I went with a quarter teaspoon each of ground aniseed (you could also use star anise), ginger and cinnamon. Don’t forget the salt and pepper. Give it a final spin in the food processor.  The sauce will be very thick indeed – it should be a spreadable consistency and not in the least pourable. It looked like a big scoop of liver ice cream – except that it was hot! Strange.

Reheat the sauce and add some cider vinegar or lemon juice to taste (or verjuice like in the original recipe – you can buy it online). If it is really thick, let it down with a little water.

#347 Sawce Noyre for Roast Capon. This was a strange one indeed – it was made up of pure liver and was therefore very rich, though when eaten with a big piece of relatively bland chicken it did balance out better. The best way to eat it, it turned out, was to spread it on some bread as those in mainland Europe did. I liked the spice combination a lot, especially the aniseed; I may use it in chicken liver pâté. Aside from that though, I think this one’s left in the history books! 4/10.
