Lina Wachtelborn Meier, The Art of German Cooking and Baking… (1922)
“ The hash of tongue, lung and heart is placed in the middle of a hot platter, the liver slices placed in a wreath around it, the meat from the head, which has been cut into neat pieces, and the brains placed on top of the hash. The gravy should be prepared before dishing out the hash. For the gravy, take one tablespoonful of flour, stir it in the butter in which the meat, brains and liver have been fried, add some of the bouillon and a little vinegar, lemon juice or white wine. Serve the gravy with the meat. ”
