Saffron is the world's most expensive spice, made from a red thread inside a crocus flower. Three threads per flower, picked by hand.
That is the whole reason for the price, since it takes something like a hundred and fifty thousand flowers to make a kilogram. It gives a deep yellow colour and a distinctive smell, and it is essential to paella, risotto alla milanese and a great deal of Persian cooking. A few threads are enough. The word also names the colour, and saffron robes are worn by Buddhist monks.
