Saffron is the world's most expensive spice, but luckily, a little goes a long way. Why is it so expensive? Saffron comes from the crocus flower, which produces only three bright red saffron threads. Since they are so delicate, they must be picked by hand.
Before adding saffron to a recipe, lightly crumble the threads between your fingers to release its oils. Saffron is very sensitive to light and moisture and absorbs other flavors and odors easily; store it away from light in an airtight container.
