Once upon a time saffron was more expensive than gold and it still is the most expensive spice in the world. Saffron is the stamen of the Crocus sativus from Turkey. The stamens are collected by hand, which is the reason for the high price. Between 200 and 500 stamens are needed for one gram of saffron.
Saffron has been used for centuries for its colour (red-yellow) and taste. Saffron strands need to be broken and soaked in hot water. It is used with shellfish and rice dishes.
The taste can be described as exotic and a bit bitter. Saffron tea is known for its warming and comforting effect. Saffron is also used as a dye.
