Martian bread and green tomato jam

Space recipe 'Martian bread and green tomato jam': this bread is a perfect combination of the genuine flavour of wheat and the sweet acidity of the tomato. A green tomato jam is presented as a side dish complementing the flavours of the main course. The basic ingredients are wheat and tomatoes, both envisioned to be grown in space, on Mars or other planets. The recipe was developed for ESA, in a research project defining food and nutrition for astronauts on future long-duration space missions.
