Tomato paste is a thick, concentrated paste made from tomatoes. It is used as a base for many sauces, soups, and stews. Tomato paste is also a good source of lycopene, an antioxidant that has been linked to a number of health benefits.
Making tomato paste is a simple process. First, tomatoes are washed and chopped. Then, they are cooked until they are soft and have released their juices. The cooked tomatoes are then strained to remove the seeds and skin. The resulting liquid is simmered until it has thickened into a paste.
