Saffron is considered the world’s most valuable spice by weight. Saffron is actually harvested from the stigma of flower Crocus Sativus. Crocus Satisvus produce large sterile, rich lilac flowers with distinctive purple veins. It is named after its three long, deep-red stigmas, which are commonly called saffron threads. The flower is commercially cultivated and harvested for these stigmas. The spice is derived from the stigma and later used for coloring and flavoring the food.
Depending on the size of harvested stigmas, 50,000–75,000 Crocus Sativus plants are needed to produce about 1 pound of saffron. Each flower only produces three stigmas, which are carefully picked by hand. The flowers must be harvested before noon time because they wither easily. This process is tedious and meticulous. This explains why saffron spice came to be so precious as to be called the red gold.
