Cassia is an aromatic bark, similar to cinnamon, but differing in strength and quality. Its bark is darker, thicker and coarser, and the corky outer bark is often left on. The outer surface is rough and grayish brown, the inside barks is smoother and reddish-brown. It is less costly than cinnamon and is often sold ground as cinnamon. When buying as sticks, cinnamon rolls into a single quill while cassia is rolled from both sides toward the centre so that they end up resembling scrolls. Cassia buds. Cassia buds resemble cloves. They are the dried unripe fruits about 14 mm (1/2 in) long and half as wide. It is native to Burma and grown in China, Indo-China, the East and West Indies and Central America.
One of the oldest spices known to man. It has a strong characteristic aroma and flavor. We may sometimes hear cinnamon refer to as cassia. This term is used to distinguish between the Southeast Asia and the Ceylon type of cinnamon. Almost all of the cinnamon consumed in the United States is derived from trees grown in Southeast Asia. Nowadays cinnamon is used to flavor bakery and dairy products, as well as drinks.
Cassia-cinnamon is such a familiar and beloved spice it needs little introduction. A global favorite for its delicious aromatic flavor.

Botanical Name: Piper nigrum
Plant Family: Piperaceae
Country of Origin: India
Plant Part: White Peppercorns
Growth Method: Wild Harvest
Extraction Method: Steam Distillation
Color: Clear
Consistency: Thin
Strength of Aroma: Medium
Pepper is a perennial vine of the Piperaceae family indigenous to the Malbar coast of India. It is now cultivated in most tropical parts of the world. Pepper bears clusters of small flowers and small spherical fruits that turn red when they ripen. The berry-like fruits eventually become the peppercorns, and each one bears a single seed. The hot spice of White Pepper is made from its berries. It is the fully mature fruits from which the soft, fleshy outer layers had been ground off before drying.
The berries of the pepper plant are called peppercorns and these plants are native to southern Asia. This plant was the main spice the European explorers were looking for when they discovered the New World. It still accounts for one fourth of the spice trade in the world.
Did you know that white and black pepper come from the same plant? The white variety is allowed to fully ripen on the vine, as opposed to the black peppercorns, which is why it costs a bit more. The skins are peeled off and the inside of the peppercorn is white. White peppercorns have an earthy flavor whereas black peppercorns simply give heat to a dish.
The white ones are popular in Mexican, Indian, and Asian dishes, perhaps because a lot of these recipes are spicy and earthy already and the white pepper complements the overall flavor of the dish. If you want to use white pepper, it is best to buy whole peppercorns because the flavor is longer lasting. Peppercorns start to lose their potency when you grind them, which is why freshly ground pepper is usually recommended.
Ginger root
Botanical name: Zingiber officinale Linn.
Family: Zingiberaceae.
Ginger oil and oleoresins are the volatile oil derived by steam distillation of ginger and oleoresin. It is obtained by percolating the powdered rhizomes of Ginger, Zingiber officinale with volatile solvents. Ginger contains 1-2 percent of volatile oil, 5-8 percent of pungent acrid oleoresin and starch. Zingiberene is the chief constituent in the oil of ginger. Oil is employed for flavoring all kinds of food products and confectionary and finds limited use in perfumery. Oleoresin, commercially called Gingerin contains pungent principles viz. gingerol and shogaol apart from the volatile oil of ginger and is used as an aromatic, carminative, stomachic and as a stimulant.
Oleoresin from ginger is obtained conventionally by extraction of dried powdered ginger with organic solvents like ethyl acetate, ethanol or acetone. Commercial dried ginger yields 3.5-10.0 per cent oleoresin. Ginger oleoresin is a dark brown viscous liquid responsible for the flavour and pungency of the spice.
Ginger of commerce or `Adrak` is the dried underground stem or rhizome of the plant, which constitutes one of the five most important major spices of India, standing third or fourth, competing with chillies, depending upon fluctuations in world market prices, world market demand and supply position.
Ginger, like cinnamon, clove and pepper, is one of the most important and oldest spices. It consists of the prepared and sun dried rhizomes known in trade as `hands` and `races` which are either with the outer brownish cortical layers (coated or unscraped), or with outer peel or coating partially or completely removed.
Ginger requires a warm and humid climate. It is cultivated from sea level to an altitude of 1500 meters, either under heavy rainfall conditions of 150 to 300 cm or under irrigation. The crop can thrive well in sandy or clayey loam or lateritic soils.

Ginger Oleoresin is obtained by extraction of powdered dried ginger with suitable solvents like alcohol, acetone etc. Unlike volatile oil, it contains both the volatile oil and the non-volatile pungent principles for which ginger is so highly esteemed. Concentration of the acetone extract under vacuum and on complete removal of even traces of the solvent used, yields the so called oleoresin of ginger. Ginger oleoresin is manufactured on a commercial scale in India and abroad and is in great demand by the various food industries.
Mace
Botanical: Myristica fragrans
Family: N.O. Myristicaceae
Hindi Name: Mace - Javitri
General Description: Nutmeg, spice consisting of the seed of the Myristica fragrans, a tropical, dioecious evergreen tree native to the Moluccas or Spice Islands of Indonesia.
Geographical Sources
The nutmeg tree, Myristica fragrans, is indigenous to the Moluccas in Indonesia but has been successfully grown in other Asian countries and in the Caribbean, namely Grenada. Banda Islands, Malayan Archipelago, Molucca Islands, and cultivated in Sumatra, French Guiana
Composition -> Nutmeg and mace contain 7 to 14 percent essential oil, the principal components of which are pinene, camphene, and dipentene. Nutmeg on expression yields about 24 to 30 percent fixed oil called nutmeg butter, or oil of mace. Dried kernel of the seed.
Varieties -> Whole nutmegs are grouped under three broad quality classifications:
1. Sound: nutmegs which are mainly used for grinding and to a lesser extent for oleoresin extraction. High quality or sound whole nutmegs are traded in grades which refer to their size in numbers of nutmegs per pound: 80s, 110s and 130s (110 to 287 nuts per kg), or 'ABCD' which is an assortment of various sizes.
2. Substandard: nutmegs which are used for grinding, oleoresin extraction and essential oil distillation. Substandard nutmegs are traded as 'sound, shrivelled' which in general have a higher volatile oil content than mature sound nutmegs and are used for grinding, oleoresin extraction and oil distillation; and 'BWP' (broken, wormy and punky) which are mainly used for grinding as volatile oil content generally does not exceed 8%.
3. Distilling: poor quality nutmegs used for essential oil distillation.Distilling grades of nutmegs are of poorer quality: 'BIA' or 'ETEZ' with a volatile oil content of 8% to 10%; and 'BSL' or 'AZWI' which has less shell material and a volatile oil content of 12% to 13%.
Method of Processing -> When fully mature it splits in two, exposing a crimson-coloured aril, the mace, surrounding a single shiny, brown seed, the nutmeg. The pulp of the fruit may be eaten locally. After collection, the aril-enveloped nutmegs are conveyed to curing areas where the mace is removed, flattened out, and dried. The nutmegs are dried gradually in the sun and turned twice daily over a period of six to eight weeks. During this time the nutmeg shrinks away from its hard seed coat until the kernels rattle in their shells when shaken. The shell is then broken with a wooden truncheon and the nutmegs are picked out. Dried nutmegs are grayish-brown ovals with furrowed surfaces. Large ones may be about 1.2 inches long and 0.8 inch in diameter.
Taste and Aroma: Nutmeg has a characteristic, pleasant fragrance and slightly warm taste
