Cuminum cyminum or better known in the plain language as Cumin is indeed one of the most popular Spices after black pepper. It is used to make dishes highly aromatic and flavourful. Produced in Iran, expect high quality Cumin Ground at a fraction of its cost. Note that using the steam sterilised version of Cumin Ground is more appropriate for cooking due to its zero bacteria content and naturally preserved flavours. http://en.wikipedia.org/wiki/Cumin
