Tomato paste

Tomato paste is a thick paste made from tomatoes, which are cooked for several hours to reduce water content, straining out seeds and skins, and cooking the liquid again to reduce the base to a thick, rich concentrate. It is used to impart an intense tomato flavour to a variety of dishes, such as pasta, soups and braised meat. It is used as an ingredient in many world cuisines.

By contrast, tomato purée is a liquid with a thinner consistency than tomato paste, while tomato sauce is even thinner in consistency.
