German Soup. Take coney flesh, fowls or veal, and cut in pieces: then half cook in water, then fry in bacon fat; then have finely minced onion in a pot, on the coals, and some fat in the pot, and shake the pot often: then grind ginger, cinnamon, grain of Paradise, nutmegs, livers roasted on a spit on the grill, and saffron mixed with verjuice, and this is the yellow coloring and the liaison. And first bread browned on the grill, ground and sieved; and at serving, put three or four pieces of your meat in the bowl and the soup over, and sugar on the soup.
