We had something similar in Vienna in 2010 - it was a perfect little pyramid shape, maybe three inches square at the base and as high as that, and it was filled with seasoned bits of ground beef suspended throughout, with a little curl of carrot here, and celery leaf there.Can't believe nobody has mentioned a traditional aspic with clearish beef broth, bits of animal protein, HB eggs, cheese, veges, etc in it, arranged to make a pleasing mosaic like pattern. There's a recipe with ideas in my Hubert Keller cookbook with picture. It's something I've thought about making from time to time.
