Cloves are the aromatic flower buds of a tree in the family Myrtaceae, Syzygium aromaticum (sɪˈzɪdʒiːəm_ˌærəˈmætɪkəm). They are native to the Maluku Islands (or Moluccas) in Indonesia, and are commonly used as a spice, flavoring, or fragrance in consumer products, such as toothpaste, soaps, or cosmetics. Cloves are available throughout the year owing to different harvest seasons across various countries.
The word clove, first used in English in the 15th century, derives via Middle English clow of gilofer, Anglo-French clowes de gilofre and Old French clou de girofle, from the Latin word clavus "nail". The related English word gillyflower, originally meaning "clove", derives via said Old French girofle and Latin caryophyllon, from the Greek karyophyllon "clove", literally "nut leaf".
The clove tree is an evergreen that grows up to tall, with large leaves and crimson flowers grouped in terminal clusters. The flower buds initially have a pale hue, gradually turn green, then transition to a bright red when ready for harvest. Cloves are harvested at long, and consist of a long calyx that terminates in four spreading sepals, and four unopened petals that form a small central ball.
Clove stalks are slender stems of the inflorescence axis that show opposite decussate branching. Externally, they are brownish, rough, and irregularly wrinkled longitudinally with short fracture and dry, woody texture. Mother cloves (anthophylli) are the ripe fruits of cloves that are ovoid, brown berries, unilocular and one-seeded.
Blown cloves are expanded flowers from which both corollae and stamens have been detached. Exhausted cloves have most or all the oil removed by distillation. They yield no oil and are darker in color.
Cloves are used in the cuisine of Asian, African, Mediterranean, and the Near and Middle East countries, lending flavor to meats (such as baked ham), curries, and marinades, as well as fruit (such as apples, pears, and rhubarb). Cloves may be used to give aromatic and flavor qualities to hot beverages, often combined with other ingredients such as lemon and sugar.
