At a price of $2,000 to $10,000 a pound, saffron is far and away the most expensive food on earth, way more than truffles, caviar, and real balsamic vinegar. Its history is epic; its flavor is revered. International organizations employ lab equipment to fuss over grading crops for flavor, color, and richness. And its longstanding coveted status has borne a tradition of adulteration, embargo, and conspicuous consumption that can only be characterized as grotesque. So what's the deal with this stuff? Is it worth all the fuss? And what, at the end of the day, can you really do with it?
First, an explanation of its price. Saffron threads are the stamens of the crocus, a high-maintenance flower whose climatory pickiness is matched only by its fickle yields. Each flower, which blooms for one week of the year, produces about three stamens which must be picked by hand (with the greatest delicacy, of course) and dried (delicately again!). 150 flowers and substantial labor are needed to produce a single gram of saffron; it's only as affordable as it is because harvesters aren't paid much at all. There are less expensive varieties available, but real saffron has a high base rate of expense that its price just can't sink below.
