Cayenne pepper and Chilli, Capsicum frutescens spp.

Cayenne and chilli are both prepared by blending powder from the seeds and pods from a number of different types of chilli. The ripe pods should be roasted until dry and dark and then ground finely. The powder should be used sparingly with fish and other seafood dishes, savoury egg dishes, stews, casseroles and hot sauces. Fresh chilli should be only eaten in small amounts and with great care.

The liquid inside the nut can be poured out after one of the eyes has been pierced. The flesh can be scraped out after the nut has been broken open.

Coconut milk is prepared by mixing equal quantities of shredded flesh and hot water and kneading them together. The milk is then separated out through a sieve. Some force is necessary to extract all the liquid. The liquid inside the coconut can also be used in place of water to make coconut milk. The milk is used to thicken curries and rice dishes and can be used as a replacement for dairy milk in desserts. Coconut can be used with fish as well as bread, cakes and sweets.

Coconut when fresh contains 4% protein, 38% fat, 11% carbohydrate, 4% fibre 1% minerals and small amounts of vitamins B1, B2, B5, and C. Dried coconut contains 62% fat and 5.5% protein.

Mace, Myristica fragrans

Mace is the powdered covering of the nutmeg seed . It does not keep well, so should be purchased in small quantities. It can be added in very small amounts to both sweet and savoury dishes, particularly creamed soups, casseroles and milk puddings.

Maize - the same as Cornmeal, Zea mays

This cereal was originally cultivated in the Americas but is now a staple crop worldwide in all but the coldest regions. Different strains are grown for use as a vegetable, for making pop-corn and for flour. White maize flour can be included in most flour mixtures for bread or cakes. The finest flour is called cornflour. In the UK this is always pure maize starch but in other countries may include some wheat flour.

Maize is mostly starch, 3.5% fat and a source of iron, and the yellow forms contain the pigment carotene, a precursor of vitamin A. Maize is deficient in most other nutrients. The ripe grains of maize are treated by boiling in a 5% lime solution. This helps remove the gelatinous hulls which must be washed away together with the lime solution before being ground into flour. This treatment also helps to improve its nutritional value.

The freshly treated and ground moist flour is used in Mexico to produce tortillas. These are much harder to make from dry flour. Masa harina is a dry powder made from this treated maize and can be used to make tortillas.

Polenta is a partly cooked maize meal.

Corn oil is 56% unsaturated fat.

The grain stores extremely well and has 10% protein, the highest iron level of any cereal, and is an excellent source of potassium and magnesium. It also contains niacin and small amounts of B group vitamins.

In Africa the grain is often ground to a flour and used to make a porridge. The flour can be used as part of a mixture of flour to make breads. The grain can also be cooked whole in the same way as rice but it absorbs far more water. Use 4 or more measures of water to one measure of millet. It should be boiled for about 40 minutes.

Millet flakes are precooked by steaming before being flattened and are much quicker to use . The larger green grained millets are better to eat than the small yellow grained millet

Mint, Mentha spp.

There are many varieties of mint in cultivation, only some of which are good to eat. Those best known are spearmint and applemint.

Sugar

Sugar is produced from the tropical sugar cane, Saccharum officinarum, and the temperate sugar beet, Beta vulgaris. The sugar produced from these crops is nutritionally identical and contains no vitamins or minerals.

Sunflower, Helianthus annuus

The seeds of sunflower can be eaten raw or crushed and used in cakes and biscuits. Sunflower seeds have 22.5% protein and are an excellent source of the minerals calcium, magnesium, iron and potassium as well as the vitamins thiamin, niacin, and E.

Sunflower oil is high in polyunsaturates and vitamin E and also contains vitamins A and D.

Sweet Corn, Corn on the Cob, Zea mays

Varieties of Corn which have higher sugar levels in the grain are eaten as a vegetable. Sweet Corn can be added to soups and stews. It is a good source of iron.

Tapioca, Cassava, Manioc, Manihot utilissima

This is one of the most important food crops of the wet tropics. The swollen roots are often poisonous and partly for this reason is almost immune to attack by pests. The roots are peeled, crushed and the starch washed out of them. This starch is then dried to form pearl or flake and more usefully a fine flour. These have little nutritional value other than from the starch but the flour is useful for general baking when mixed with other flours.

Tarragon, Artemisia dracunculus

Vanilla, Vanilla fragrans

This flavouring comes from the long thin seed pod of a tropical climbing orchid.

The pods can be kept in a jar of sugar when they impart their flavour to the sugar, or the flavour can be extracted by steeping a pod in the liquid of the dish for one hour. Pods used in this way can be dried and used again. The pod can also be ground and used as a powder.

Walnut, Juglans regia
