Canned tomato paste is one of the main condiments and cooking bases in Iranian cuisine and many other cultures, which is produced by concentrating and cooking fully ripe and high-quality tomatoes in industrial factories. In this process, tomatoes, after peeling and separating the seeds, are heated and evaporated to the desired concentration, then packaged in sterile metal cans to preserve their taste, color and nutritional value for a long time. As a strong and natural flavoring, this product is indispensable in preparing various stews, sauces, soups and dishes such as gheeme and ghorme sabzi, and due to its ease of use, time saving and uniformity of taste, it has a permanent place in every kitchen cupboard.
