Tomato paste is a thick, concentrated condiment made from ripe tomatoes that have been cooked down to remove most of their water content, resulting in a rich and flavorful base for many dishes. It has a smooth texture, a deep red color, and a bold, tangy taste that brings out the essence of tomatoes in a concentrated form. This kitchen staple is used worldwide to add depth and complexity to sauces, soups, stews, and more.
The preparation of tomato paste involves slow cooking tomatoes until they break down into a thick sauce, followed by straining to remove seeds and skins. The sauce is then reduced to a paste by simmering it further, creating a concentrated, full-bodied flavor. Tomato paste is often sold in cans, tubes, or jars, making it easy to store and use as needed.
