Discover the best ways to store leftover tomato paste to maximize its shelf life. Learn handy tips for using tomato paste and ensuring the best quality for your future recipes.
Tomato paste is a staple ingredient in many kitchens, known for its concentrated flavor that enhances a variety of dishes. The shelf life of tomato paste is important for those who rely on its depth and richness to elevate their cooking. Whether in canned form or stored in the freezer after opening, the longevity of tomato paste can vary based on how it's stored.
Unlike other tomato products, tomato paste is highly concentrated because it is cooked longer and develops its thick, well-rounded consistency. This process gives it a sweeter, milder flavor compared to tomato purée, making it a handy addition for thickening and flavoring dishes. Understanding the best way to store leftover tomato paste is essential for maintaining its quality as a pantry staple.
Unopened canned tomato paste can last 18 to 24 months when kept in a cool, dry place and usually remains safe to use after this period if not damaged. However, once opened, its shelf life decreases significantly. Proper handling and storage are crucial for extending its usability for future recipes.
