Sawce Noyre · Sawce Noyre for mallard · Sawce Noyre for Capons y rosted · Sawse noire
Two dark sauces from The Forme of Cury, about 1390: one for mallard from bread and boiled blood, the other for roast capon from liver, bread and spices. Both are historical preparations.

Sawse noire is a dark sauce, coloured by blood or liver. The Forme of Cury gives two versions, one for mallard and one for roast capon, and the two differ in their main ingredient and in how the mixture is strained or ground.
Both are boiled before serving and are served with the bird they were made for. They are historical preparations, not a single sauce with two names.
In the mallard version, bread thickens the blood and vinegar sharpens it, and straining through a cloth removes the coarse material. In the capon version, the liver gives body and the spices give warmth, and verjuice replaces the vinegar.
The record gives no quantities, so the balance of blood or liver to bread and acid is not known. Raw blood and liver are not ingredients a modern kitchen should handle without current food-safety guidance.
The method names no temperatures, timings or holding conditions. Its boiling step is the only heat treatment in the text as read.
Historical inclusion does not endorse recreating the raw materials or the holding practices of the period. No preserving process is established, and no safety claim is made for either sauce.
Both sauces are recorded in The Forme of Cury, an English recipe collection compiled about 1390 and attributed to the master cooks of King Richard II.
Blood and liver are raw materials with food-safety requirements. The historical method does not establish how they were handled, and no safety claim is made here. Do not treat the medieval practice as a present-day instruction.
