Unglazed pottery from two sites in the Libyan desert have come up trumps – with evidence of plants being cooked, or heated up to make the plant fibres more palatable. Residues of food-stuff processed within the fabric of unglazed cooking pots have been analysed and they indicate a wide range of plants were being used as a food resource, such as wild grains, leafy plants and aquatic plants. They date back 10,000 years ago when the Sahara was well watered and fertile.
