Space recipe 'Spirulina Gnocchis': This dish has been created in the traditional way of making gnocchi. Beyond the nutritions aspect provided by the spirulina, its original green colour marries perfectly with the tomato sauce. The basic ingredients are potatoes, spirulina and tomatoes, all envisioned to be grown in space, on Mars or other planets. The recipe was developed for ESA, in a research project defining nutrition for astronauts on future long-duration space missions.
