Watermelon comes from Egypt and was first grown on the banks of the Nile. Later, the Israelites extended its cultivation to Mediterranean countries and nowadays it has become a typical fruit of warm and temperate climates. The main producing countries are: Spain, Italy, Turkey, Greece, China and Japan.

It is characterised by its smooth, hard skin, with a 2 - 4 cm thickness which is green, light green or yellowy green. Its flesh can be red, pink or yellow, and it usually has shiny black, brown or white seeds.

It is one of the largest fruits in the market and can weigh as much as 10-15 kilograms, although the most common ones range between 3 and 8 kilograms.  Production in Spain takes place between the months of June and September.

Uses of watermelon

Watermelon is a very versatile fruit and combines perfectly with many foods. It can be eaten on its own or in a fruit salad, either before or after meals, and is also interesting to use in salads, sorbets, juices or ice creams.

The seeds can be eaten, in fact, in many Asian countries they are eaten as an aperitif, both toasted and fried, and there are even places where they are used to make bread.

Advice for buying and conservation

To know if a watermelon is ripe, check if it has a yellow creamy stain on its skin, a sign  indicating the area of contact of the fruit with the floor while it was ripening. When tapping it with your fingers or the palm of your hand, it should sound “hollow” and with dark green watermelons, you should be able to easily scratch the skin with your nail.

You can often find half watermelons in the supermarket, perfect for smaller families.  To choose the best, check that the flesh is firm and contains quite a lot of water.

The whole watermelon, thanks to its thick skin can be conserved perfectly for two or three weeks at room temperature, as long as it is stored in a cool dry place.  

Once cut, it must be eaten quickly so it doesn’t lose its flavour and properties.  It is worth keeping in the fridge, but always in the least cold part because it is sensitive to low temperatures. It is recommended not to store it below 7-10ºC.
