tomato paste

Tomato paste is a thick, concentrated condiment produced by cooking tomatoes (Solanum lycopersicum) for hours, straining out seeds and skins, then cooking the resulting liquid further until it reaches a dense, deeply colored paste. Originating from regions around the Mediterranean where tomatoes were cultivated after their introduction from the Americas, tomato paste represents one of the most economical ways to preserve tomato flavor in concentrated form. The paste is characterized by its deep red to burgundy color, intense umami-rich flavor, slight acidity, and smooth, viscous texture. Commercial tomato paste typically contains no additives beyond salt, though some variations may include garlic, basil, or oils.

The concentration level of tomato paste varies by producer and intended use; paste typically represents tomato solids concentrated to roughly 25-30% by evaporation, creating a product that is approximately three to six times more concentrated than tomato puree.

Tomato paste functions as a foundational building block in numerous cuisines, particularly Mediterranean, Latin American, and Asian cooking traditions. It is essential in Italian sauces (ragù, arrabbiata bases), Spanish sofrito preparations, and Middle Eastern stews and marinades. The ingredient is also fundamental to ketchup, barbecue sauces, and curry bases across Asian cuisines. In the kitchen, small amounts of tomato paste are typically bloomed in oil or fat before adding liquid to develop flavor, preventing the harsh acidity that can result from direct hydration. It serves to deepen tomato flavor, add body, and enhance umami in soups, braises, sauces, and marinades. Because of its concentrated nature, a small quantity yields significant flavor impact, making it an economical choice for kitchens seeking intense tomato character year-round.
