Tomato sauce is a staple in many cuisines around the world, serving as the foundation for numerous dishes, from pasta and pizza to stews and soups. However, once you’ve opened a jar or made a fresh batch, questions about its longevity often arise. Understanding how long tomato sauce lasts in the fridge is crucial for maintaining food safety and quality. This article delves into the world of tomato sauce, exploring its shelf life, factors that influence its durability, and tips for extending its freshness.
Introduction to Tomato Sauce
Tomato sauce, in its simplest form, is a sauce made from tomatoes, commonly used in Italian and Mediterranean cuisine. The basic ingredients include tomatoes, onions, garlic, and herbs, with variations depending on the recipe and desired flavor profile.
