Throughout human history, eggs and bone marrow have been one of the most sought-after sources of protein and fat. In fact, the need to smash apart bones to get at the marrow may have been one of the forces that drove our ancestors to adopt stone tools. In a continuation of these ancient tastes, the lab-stylized marrow bone takes the buttery goodness of marrow and packages it with the convenience of an egg.
These dainty ‘eggs’ aren’t filled with yolk, however, but with snow-white cultured marrow. The 3D-printed exterior is inspired by the ‘test’, or shell, of a sea urchin, and adds valuable calcium to a dish. Lab-grown marrow bones lend meaty notes to vegetarian soups, and taste delicious when roasted and spread on toast – no stone bludgeon required.
