Clove is the rich, brown, dried unopened flower bud of Syzgium Aromaticum, an evergreen tree in the Myrtle family. Clove has a strong aroma and a fiery burning taste. It is native to the Molluca islands of North East Indonesia. Clove stem is the stem of the clove bud flower. Normally, the stem is separated from the flower bud during the drying and sorting process. It is however rich in oil (5-8%) and preferred as a cheaper source to obtain clove oil.
