It belongs to the legume family, which is the same family as beans. These trees are native to the Middle East and the Mediterranean region. They are very strong and can survive in hot, dry places. Scientists call them xerophytes because they are built to handle long droughts.

The trees have thick trunks with rough brown bark. Their leaves are long and grow in a pattern called pinnate. This means many small leaflets grow along a single stem.

Growing fruit on a carob tree is a slow process. It takes a full year for the seed pods to develop and ripen. Most carob trees are dioecious, which means they are either male or female. Only the female trees produce the sweet fruit.

When the pods are ripe, they fall to the ground. Animals like swine, or pigs, eat these sweet pods. This helps the tree spread its seeds to new places through the animals. The seeds themselves are very hard and stay inside the pods.

People have used the carob tree for a very long time. The name "carob" comes from the Arabic word kharrūb. In some places, people call it "St. John's bread."

The seeds are so important that they helped name the carat. A carat is a unit used to measure the weight of gemstones. In the past, carob pods were even used as food during times when food was scarce. This shows how much people have relied on this tree for survival.

There are many different ways to use the carob harvest. The fruit pods have two main parts: the pulp and the seeds. The pulp makes up about 90% of the weight. People grind this pulp into a powder or small chips. Because of its color and taste, it is often used as a substitute for chocolate.

The seeds make up the other 10% of the weight. These seeds are used to make carob gum. This is a thickening agent used to change how food feels in your mouth.

Today, many countries grow carob for food and gardens. Spain is the largest producer of carob in the world. Italy and Morocco are also very important producers.

In Malta, people even make a traditional sweet called karamelli tal-harrub. You might find carob ingredients in your favorite cookies or cakes. It is a wonderful example of how a single tree can help many different people.
