FALSE GRAIN DISH. Cook in water and wine livers and giblets of poultry, or meat from veal, or from a leg of pork or mutton, then chop it very finely and fry in lard: then grind up ginger, cinnamon, clove, grains, wine, verjuice, beef bouillon or juices of whatever meat you are using, and lots of egg-yolks, and pour it over your meat, and put it on to boil well. Some add saffron, as it should be yellowish in colour, and others add burnt bread, ground and sieved, for it should be thickened and also eggs and bread, and it should be tart from the verjuice. And in serving, over each bowl, sprinkle powdered cinnamon.
