Cloves are the dried, unopened flower buds of the tropical evergreen tree Syzygium aromaticum. When dried, they turn to rust-brown four-pointed flower buds with tapered stems resembling small nails. Clove is a warm, pungent spice with a strong aroma. It is indigenous to the Moluccas, the fabled Spice Islands of Indonesia. Today it is cultivated in Brazil, the West Indies, Mauritius, Madagascar, India, Sri Lanka, Zanzibar and Pemba. The most important production area is the island of Pemba; the whole island of Pemba is covered with clove gardens.
Cloves trees thrive in the tropics near the sea. Heavy rainfall is a must for the growth of the tree. And a dry summer season is needed for harvesting and drying the spice. Twice a year clove clusters are picked by hand before the buds open. The buds are separated from the stems and spread on mats to dry in the sun for several days until they turn dark brown. They lose two-thirds of their weight after drying.
The aroma of clove is stronger than most other spices and only a small quantity of the spice is used in most recipes. Like any other spice cloves are best bought whole. The flavor quickly deteriorates when it is powdered or crushed.

The history of cloves, another spice indigenous to the Moluccas Islands, is similar to that of nutmeg and mace. Trade between the small island of Ternate, called the Clove Island, and China goes back at least 2500 years. Arab traders introduced cloves to Europe during the days of the Roman Empire. Cloves along with nutmeg became popular in Europe by the eighth century. Spice trade brought great wealth to Venetian traders. The lure of cloves and nutmeg attracted the Portuguese to the Spice Islands in 1514. The Dutch followed them by 1605, and held control over the trade until late in the eighteenth century. The Dutch maintained monopoly of clove trade during all of the seventeenth century and earned high profits. The French introduced the clove tree into Mauritius. Later the cultivation expanded to Guiana, Brazil, Zanzibar and West Indies. Spice trade brought immense wealth to the Venetians, Portuguese, Spanish, the Dutch and the British. This was followed by the extraordinarily successful entry of the United States in 1672 into the spice trade. Salem, Massachusetts became the capital of spices in the first half of the 19th century.
