- Egurdouce. The term expresses piccante dolce, a mixture of sour and sweet; but there is nothing of the former in the composition. Vide Gloss.
Translated from middle English:
Egurdouce means sweet and sour, and as noted  there is no sweet in the excerpted recipe. I believe this is easily explained when using Mead as a replacement of red wine; this would have been common practice to sweeten a recipe. This recipe starts with the meat of rabbit (conynges), lamb (ref: Pleyn Delit) or goat, cut in to pieces of raw meat, fry them in butter or shortening, take raisins of Coraunce (raisons or currants), and fry them. Take and parboil onion and cut them into small pieces. Add the onions to the frying meat. Take red wine, sugar, pepper, powdered ginger, cinnamon, salt and add to the meat and onions, add butter and serve.
