Fruits with flavour

Oranges, mandarins, grapefruits, pomelos, kumquats, lemons and limes are all citrus fruits grown in the Pacific Islands. Whether sweet or sour and acid, these nutritious fruits are enjoyed for their flavours. They can be eaten alone or with other foods so that the citrus gives that food a special flavour.

Many parts of citrus - the fruit juice, peel and leaves - can be used. Using all parts of a fruit means that none of its food value is wasted. Citrus is a valuable local food because of its wide use as a flavouring.

A large variety

Citrus fruits belong to the family with the scientific name Citrus. They grow on trees that have dark-green, waxy leaves and sweet-smelling flowers.

Citrus trees grow only on some Pacific Islands. The roots of citrus trees must be able to get water at a depth of 1.2 metres (4 feet) in order to grow well. They need plenty of water, especially when the fruit is growing. The water must be salt free which is why citrus trees do not grow well on most atolls.

Citrus trees are planted from the seeds of ripe fruit. Wash and dry the seeds and plant them 1 cm (½ inch) deep in a partly shady place. When the plants are 20 cm (8 inches) high, they are ready to be transplanted. Choose only those plants that are healthy. Plant them in a sunny place where there will be enough room for them when they are fully grown.

The size of citrus fruits varies from small limes to large pomelos. Citrus fruits should be picked when ripe.

Local fruits are best

Citrus fruits are protective, health-giving foods because they contain vitamins the body needs to stay healthy. They are good sources of Vitamin C, which keeps body tissues strong, helps the body to use iron, and helps chemical actions in the body. There is a lot of Vitamin C in the peel of citrus fruits as well as the flesh

Because of its high Vitamin C content, the juice is good for babies. The stronger flavoured citrus juices should have water added to them so that babies will like the taste.

Citrus is also a fair source of Vitamin A which is needed for proper growth, healthy eyes and protection from disease.

Eating locally grown citrus is better than eating expensive imported fruits for two reasons. Locally grown citrus is cheaper and has better food value for the money spent. Many people think that imported fruits are better than local fruits. This is not true. An example is shown in the bar charts. It is easy to see that apples, for example, do not contain as much Vitamin A and Vitamin C as oranges.

Many people buy expensive imported oranges rather than buying local oranges. They are paying more money to get the same food value. The main difference between the two kinds of oranges is that the imported oranges have been sprayed with chemicals and wax to make them a shiny and bright orange colour. Why spend money on beauty that is only skin deep? It is food value that is important.

Preparation and uses

Fruit - Citrus fruit may be eaten straight from the tree, squeezed to make juice or used in cooking and baking.

Eating citrus fruit directly from the tree is the best way to take advantage of the Vitamin C in them. Peel the fruit, remove the white skin (pith) if it is bitter, and separate it into sections. For larger citrus fruits, remove the thin coverings that hold the sections together.

Juice - Citrus juice has many uses and makes delicious drinks. To get the most juice from a fruit, roll it on a hard surface, pressing gently while rolling. Cut and squeeze out the juice.

Lemon and lime juice in particular have many uses that are both food and non-food related. Rust stains on cloth can be removed by rubbing lemon or lime juice into the stained area. Before it dries, rinse the area well with water.

Lemon or lime juice can be used as a flavouring for fish, green leaves, soups and curries. It is a good substitute for vinegar. In a low salt diet, lemon or lime flavouring can hide the fact that there is little salt. Also, it can be used in baking when vanilla flavouring is not available.

Lemon or lime juice helps keep fresh fruits and vegetables from turning brown. For this reason it can be used when freezing fruits. Dip the prepared fruit in lemon or lime juice and freeze. When the fruit is unfrozen, it will not go brown too quickly.

Making your own lemonade saves money spent on expensive cordials and soft drinks.

To make lemonade:

1. Wash and peel 1 lemon. Boil the peel in 2 cups of water to which 1 tablespoon of sugar has been added. Boil for 5 minutes.

2. Cool and remove the peel.

3. Add the juice and pulp of the lemon. Taste and add a little more sugar if needed.

4. Serve cool.

Peel - The peel of citrus fruit can be used as flavouring. It can be added to baked foods, soups, meats, sauces and desserts. To prepare citrus peel, use a small grater. Only grate off the coloured part of the peel. The white part (pith) underneath can have a bitter, unpleasant taste.

Never use the peel of imported oranges. These have been sprayed with chemicals and wax, which are harmful to your health.

Leaves - Citrus leaves are useful as well. They may be used to make a leaf tea or added to the pot when brewing regular tea. Lemon leaves are especially good for this kind of tea. Only the older, dark-green leaves should be used. Tear them into boiling water. They contain minerals that the body needs. If added to warm milk, crushed citrus leaves can make a nutritious drink for children.

Citrus leaf tea is good to drink in the evening because it contains no caffeine, which is found in tea and coffee. Caffeine can keep you from sleeping well.

To make lemon leaf tea:

1. Crush 10 lemon leaves into 6 cups of boiling water. Boil for 5 minutes. Cool for a few minutes.

2. Remove leaves and add 1½ cups milk, if desired, to the warm lemon tea and serve.

Storage and preservation

The best way to keep citrus fresh is to leave the fruit on the tree. If citrus is picked for storing, care must be taken. The peel should not be scratched or bruised, and the fruit should be picked when dry. Cut the fruit from the tree and make sure the stems are cut close to the fruit. Store in a cool place and check often to see if there are any bad pieces of fruit amongst them.

Citrus juices can be preserved by freezing them for later use. Lemon or lime juice can be frozen in ice-cube trays. When frozen, remove cubes from trays and store in plastic bags or airtight containers in the freezer. The cubes can be easily used as flavourings.

Drying grated citrus peel makes it available for later use. Grate the citrus peel and spread it on a tray. Dry the grated peel in the sun or in a solar dryer. When it is dry, store it in an airtight container.
