Tomato paste is a thick, concentrated form of tomato made by cooking down fresh tomatoes to remove most of their water content. This process intensifies the flavor, resulting in a rich, deep taste that enhances various dishes. It is commonly used in sauces, soups, and stews, providing a robust base for many recipes. Typically sold in small cans or tubes, tomato paste is a staple in many kitchens. It is often used in Italian cuisine for making pizza sauce and pasta sauce, but it can also be added to chili or casseroles for added depth and richness.
