Making plum jam. First, the plums are picked from the trees. Then, they are transported to the factory by trucks. The plums are inspected carefully to check their quality and only good ones are used to make the jam. Sugar, water and other ingredients are heated to very high temperatures to kill any germs. Once the jam is in glass jars, the jars are labelled with the name and the company. The jam is distributed to different shops and, finally, it is sold to customers.
