We grind cloves in small batches every week, for an incredibly strong flavor. The essential oil eugenol is responsible for the bitter, numbing flavor in cloves, and our high-oil ground cloves are so strong, we highly recommend storing them in glass or ceramic containers.
Cloves are originally only native to a tiny group of islands near Indonesia, though they are now grown around the world. During the peak of the Age of Exploration, various European nations battled each other over control for these Spice Islands, which were the only place in the world one could find precious cloves and nutmeg. The buds of clove trees turn pink just before they blossom, marking the point at which they must be harvested quickly. A single tree yields around seven pounds of this rich, sweet spice.
