The world’s most expensive spice, saffron is the stigma plucked from the purple-flowered crocus. Each flower has only three stigmas, and a five-acre plot yields between 500 and 750g of this hand-picked spice.
Saffron grading is lab tested, with A and B being the highest of four grades. A-grade has the deepest red and is the most concentrated in flavour; B-grade, which comes from a different section of the stigma closer to the base of the flower, is still of exceptional quality.
