-ounce can of tomato paste

Tomato paste is a concentrated form of tomato solids derived from cooked, strained tomatoes (Solanum lycopersicum), with the majority of seeds and skins removed. The paste is produced by cooking tomatoes for several hours to reduce their liquid content, then straining the pulp through a fine sieve to achieve a smooth, dense concentrate. The resulting product contains significantly higher levels of tomato solids and flavor compounds than whole tomatoes, with a deep red color and intense, slightly acidic taste. Commercial tomato paste typically contains 25-30% tomato solids and is often preserved with salt and may include citric acid as a preservative.

Tomato paste serves as a versatile building block in countless cuisines, providing concentrated tomato flavor, color, and body to dishes without adding excess liquid. It is shelf-stable when canned and has an indefinite shelf life when unopened, making it a pantry staple globally.

Tomato paste functions as a flavor base and thickening agent in Mediterranean, Middle Eastern, Asian, and Latin American cuisines. It is essential in Italian ragùs, Spanish soffritos, Indian curries, and Turkish sauces. Common applications include soups, stews, braised dishes, pizza sauces, and condiments like ketchup. A small amount adds depth and umami to chili, beef stews, and marinara; larger quantities create concentrated pasta sauces and tomato-based condiments. It is typically diluted with water or broth when reconstituting to sauce consistency, or used directly in concentrated applications. Tomato paste pairs well with garlic, onions, olive oil, herbs (basil, oregano, thyme), and spices (cumin, paprika).
