Lina Wachtelborn Meier, The Art of German Cooking and Baking… (1922)
“ The gravy is usually thin, therefore add the flour and serve with the roast ; the contents of the dish must not boil, otherwise the roast will become dry. Cut the roast into slices, place them into a buttered mold, put the sardines, capers and bits of butter between them and drip the lemon juice on. Cover the mold, put it into the dish with boiling water and boil for % hours. The meat is served in the mold, the gravy heated and served with it. ”
