One should boil an old chicken whole, and take another raw chicken and cut it very small, and add thereto bacon, cut as small as peas, and ground cumin (and make therof small balls, and place them in the broth of the boiled hens. And add cumin,) saffron, and wine, pork lard, and salt to taste, and egg yolks so that it thickens evenly. This is called "kloten en honaer."
