In the first half the programme looks at Saffron. We visit the Berbers of Morocco, the origin of saffron to see the purple Crocus flowers growing in what looks like a desert. The fields are irrigated with water channels dug into the ground and Sheep dung is carried by the water to fertilize at the same time. The harvest lasts no more than a month and the flowers are picked early every morning. Each bulb produces four flowers each season. During the day, the Stamens are removed and it is a social event like the picking which involves almost everyone in the village. The stamens are dried. We are told that red is the best and the deeper the red the better the saffron. Handling the flowers gives people purple fingers and the people in the area are generous with their saffron using it in drinks and a wide range of cuisine. The programme then moves to Spain which was so suitable for saffron that it became the saffron capital of the world after being conquered by the Muslims. We are told that saffron from all over the world is now brought there and traded. With saffron being so expensive it is often diluted with other spices (such as turmeric), stamens from other plants or species and even plastic and other contaminants. We got to visit one of the laboratories which does DNA testing and Spectrum analysis as it seeks to maintain the high quality of saffron and to protect it from fraud and impurities which would devalue the genuine product.
