Pure Saffron 'Mancha' - Category I, Filaments/Threads - 0.04 oz (1 g) by Altaj Crown, Spain. The worlds most expensive spice, saffron is the stigma from a small purple plant which only produces three stigmas, which are hand-picked and dried carefully. Chefs are wild for this flavorful and colorful spice, heady and supremely aromatic. Store in an airtight container in a cool, dark place.
