Saffron comes from the crocus flower and the saffron threads are thread-like stamens of those flowers. They are a dark orange colour and highly fragrant with a honey-like taste. Saffron is the most expensive spice of all because of the difficulty harvesting the saffron as each stamen is handpicked. In Indian cuisine, saffron is used in fish and rice dishes and some sweet dishes. Saffron needs to be soaked in hot water or milk for about 15 minutes before being used. Saffron is said to be a reliever for coughs, asthma and sleep problems.
