SOUP of HARE or CONEY is made thus: roast the hare on a spit or on the grill, then dismember it, and put to fry in fat or bacon: then have toasted bread-crumbs moistened with beef stock and wine, and strain, and put to boil together; then take ginger, a clove and grain; moisten with verjuice and let it be dark brown and not too thick. Note that the spices must be ground before the bread.
