Sugar cookie cubes carried on the Gemini space misions. Food can float around in 'blobs' in the weightles conditions of space, so astronauts have to eat with care. Food is specially prepared in tins or flexible packs and is often dried to save space. Food cubes were designed to be gulped down in one mouthful and were coated in gelatine to prevent crumbling. The food provided a nutritionally balanced meal but was disliked by astronauts as it lacked flavour and texture.
