Cinnamon is a spice obtained from the inner bark of several tree species from the genus Cinnamomum. Cinnamon is used in both sweet and savoury foods. The term "cinnamon" also refers to its mid-brown colour.

          Cinnamomum verum is sometimes considered to be "true cinnamon", but most cinnamon in international commerce is derived from related species, also referred to as "cassia".

Cinnamon is the name for several species of trees and the commercial spice products that some of them produce. All are members of the genus Cinnamomum in the family Lauraceae. Only a few Cinnamomum species are grown commercially for spice.

            Cinnamon bark is used as a spice. It is principally employed in cookery as a condiment and flavouring material. It is used in the preparation of chocolate, especially in Mexico, cinnamon is often used in savoury dishes of chicken and lamb. In the United States, cinnamon and sugar are often used to flavour cereals, bread-based dishes, such as toast, and fruits, especially apples; a cinnamon-sugar mixture is even sold separately for such purposes. It is also used in Turkish cuisine for both sweet and savoury dishes. Cinnamon can also be used in pickling and Christmas drinks such as eggnog. Cinnamon powder has long been an important spice in enhancing the flavour of Persian cuisine, used in a variety of thick soups, drinks, and sweets.

2. Parsley

       Parsley or garden parsley (Petroselinum crispum) is a species of flowering plant in the family Apiaceae, native to the centralMediterranean region (southern Italy, Greece, Portugal, Spain, Malta, Morocco, Algeria, and Tunisia), naturalized elsewhere in Europe, and widely cultivated as a herb, a spice, and a vegetable.

            Where it grows as a biennial, in the first year, it forms a rosette of tripinnate leaves 10–25 cm (3.9–9.8 in) long with numerous 1–3 cm (0.4–1.2 in) leaflets, and a taproot used as a food store over the winter.

          Parsley is widely used in European, Middle Eastern, and American cooking. Curly leaf parsley is often used as a garnish. In central Europe, eastern Europe and southern Europe, as well as in western Asia, many dishes are served with fresh green chopped parsley sprinkled on top. Root parsley is very common in central, eastern and southern European cuisines, where it is used as a snack or a vegetable in many soups, stews, and casseroles.

          Parsley is widely used in Middle Eastern, European, Brazilian and American cooking. Curly leaf parsley is used often as a garnish. Green parsley is used frequently as a garnish on potato dishes (boiled or mashed potatoes), on rice dishes (risotto or pilaf), on fish, fried chicken, lamb, goose, and steaks, as well in meat or vegetable stews (including shrimp creole, beef bourguignon, goulash, or chicken paprikash).

      In central Europe, eastern Europe and southern Europe, as well as in western Asia, many dishes are served with fresh green, chopped parsley sprinkled on top. In southern and central Europe, parsley is part of bouquet garni, a bundle of fresh herbs used as an ingredient in stocks, soups, and sauces. Freshly chopped green parsley is used as a topping for soups such as chicken soup, green salads, or salads such as salade Olivier, and on open sandwiches with cold cuts or pâtés.

            Persillade is a mixture of chopped garlic and chopped parsley in French cuisine.

Parsley is the main ingredient in Italian salsa verde, which is a mixed condiment of parsley, capers, anchovies, garlic, and sometimes bread soaked in vinegar. It is an Italian custom to serve it with bollito misto or fish. Gremolata, a mixture of parsley, garlic, and lemon zest, is a traditional accompaniment to the Italian veal stew, ossobuco alla milanese.

            In England, parsley sauce is a roux-based sauce, commonly served over fish or gammon.

Root parsley is very common in Central, Eastern and Southern European cuisines, where it is used as a snack or a vegetable in many soups, stews, and casseroles, and as ingredient for broth.

In Brazil, freshly chopped parsley (salsa [ˈsawsɐ]) and freshly chopped scallion (cebolinha [sebuˈɫĩɲɐ]) are the main ingredients in the herb seasoning called cheiro-verde ([ˈʃejɾu ˈveʁdʒi], literally "green aroma"), which is used as key seasoning for major Brazilian dishes, including meat, chicken, fish, rice, beans, stews, soups, vegetables, salads, condiments, sauces, and stocks. Cheiro-verde is sold in food markets as a bundle of both types of fresh herbs. In some Brazilian regions, chopped parsley may be replaced by chopped coriander (cilantro)(coentro [ˈkwẽtɾu]) in the mixture.

3. Pangium Edule

          Pangium edule (Indonesian: keluak or keluwak; Malay: kepayang) is a tall tree native to the mangrove swamps of Southeast Asia (Indonesia, Malaysia and Papua New Guinea). It produces a large poisonous fruit (the "football fruit") which can be made edible by fermentation.

            The fresh fruit and seeds contain hydrogen cyanide and are deadly poisonous if consumed without prior preparation. The seeds are first boiled and then buried in ash, banana leaves and earth for forty days, during which time, they turn from a creamy white colour to dark brown or black. The method relies on the fact that the hydrogen cyanide released by the boiling and fermentation is water-soluble and easily washed out.

              The kernels may be ground up to form a thick black gravy called rawon, popular dishes include nasi rawon, beef stew in keluwek paste, and sambal rawon. A stew made with beef or chicken also exists in East Java. The Toraja dish pammarrasan (black spice with fish or meat, also sometimes with vegetables) uses the black keluak powder.[citation needed] In Singapore and Malaysia, the seeds are best known as an essential ingredient in ayam(chicken) or babi (pork) buah keluak, a mainstay of Peranakan cuisine.
