Cloves are the aromatic flower buds of a tree in the family Myrtaceae, Syzygium aromaticum. They are native to the Maluku Islands in Indonesia, and are commonly used as a spice. Cloves are commercially harvested primarily in Indonesia, India, Madagascar, Zanzibar, Pakistan, Sri Lanka—and the largest producer, Pemba Island, just off the coast of Tanzania.
The clove tree is an evergreen that grows up to 8–12 m tall, with large leaves and sanguine 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 1.5–2.0 cm long, and consist of a long calyx that terminates in four spreading sepals, and four unopened petals that form a small central ball.
The almond is a species of tree native to the Middle East and South Asia. "Almond" is also the name of the edible and widely cultivated seed of this tree. Within the genus Prunus, it is classified with the peach in the subgenus Amygdalus, distinguished from the other subgenera by the corrugated shell (endocarp) surrounding the seed.
The fruit of the almond is a drupe, consisting of an outer hull and a hard shell with the seed (which is not a true nut) inside. Shelling almonds refers to removing the shell to reveal the seed. Almonds are sold shelled (i.e., after the shells are removed), or unshelled (i.e., with the shells still attached). Blanched almonds are shelled almonds that have been treated with hot water to soften the seedcoat, which is then removed to reveal the white embryo.
Cardamom (or cardamon) refers to several plants of the similar genera Elettaria and Amomum in the ginger family Zingiberaceae. Both genera are native to India, Pakistan, Nepal and Bhutan; they are recognised by their small seed pods, triangular in cross-section and spindle-shaped, with a thin, papery, outer shell and small black seeds. Guatemala is the biggest producer and exporter of cardamom in the world, followed by India. Some other countries, such as Sri Lanka, have also begun to cultivate it. Elettaria pods are light green while Amomum pods are larger and dark brown.
Black pepper (Piper nigrum) is a flowering vine in the family Piperaceae, cultivated for its fruit, which is usually dried and used as a spice and seasoning. The fruit, known as a peppercorn when dried, is approximately 5 millimetres (0.20 in) in diameter, dark red when fully mature, and, like all drupes, contains a single seed. Peppercorns, and the ground pepper derived from them, may be described simply as pepper, or more precisely as black pepper (cooked and dried unripe fruit), green pepper (dried unripe fruit) and white pepper (unripe fruit seeds).
Black pepper is native to south India, and is extensively cultivated there and elsewhere in tropical regions. Currently Vietnam is the world's largest producer and exporter of pepper, producing 34% of the world's Piper nigrum crop as of 2008.
Dried ground pepper has been used since antiquity for both its flavor and as a medicine. Black pepper is the world's most traded spice. It is one of the most common spices added to European cuisine and its descendants. The spiciness of black pepper is due to the chemical piperine, not to be confused with the capsaicin that gives fleshy peppers theirs. It is ubiquitous in the modern world as a seasoning, and is often paired with salt.
The Ceylon cinnamon or true cinnamon, is the dried bark of Cinnamomum zealanicum, belongs to the family Lauraceae. It is indigenous to Sri Lanka. Cinnamomum zealanicum is an evergreen perenial plant with spirally arranged, broad laminated dark green leaves having palmate venation.
Under natural conditions, the plant grows to a height of 10 - 15m with the girth of 30-50cm. When coppiced from time to time it could be maintained as bush of 2-2.5m height with multiple stems arising from its base. The flowers are small, creamy and inconspicuous developing into dark purple ovoid one seeded berries, about 1.5 - 2.5cm long.
