Saffron crocus
Saffron is a spice valued in Spanish cuisine which is very expensive. Many years ago I remember the grocery stores would keep it under lock so people couldn't steal the tiny envelopes containing a few pistils, which were valued at around $5 in those days. I can't recall even seeing these at a regular grocery for years; I shudder to think what the price might be in a specialty store.
This ingredient is essential for paella and for real Cuban yellow rice, so I decided to grow my own. A few years ago I planted about 20 bulbs of saffron in the front yard. This past week they started to bloom: this is one of the flowers of the beautiful autumn-flowering crocus. The orange three-pronged stigma is the part used for the spice. I've harvested about a baker's dozen flowers so far, hope for a few more before the season ends.
I've seen photos of the area in Spain where saffron is grown commercially--it's a fairy-tale setting of round hills and ancient windmills. The flowers are picked in the morning as they begin to open, and traditionally are processed in family kitchens. The saffron workers' hands are stained orange from stripping the stigmas from the
thousands of flowers needed to make an ounce. Yet an ounce of the spice is worth thousands of dollars.
