The art of making pizza is an age-old tradition that has been perfected over centuries, with the sauce being a critical component. Whether you’re a seasoned chef or a DIY enthusiast, understanding how long pizza sauce lasts in the fridge is essential for maintaining its flavor, quality, and safety. In this article, we’ll delve into the world of pizza sauce, exploring its shelf life, factors affecting its longevity, and tips for extending its freshness.
Introduction to Pizza Sauce
Pizza sauce, also known as tomato sauce, is a fundamental ingredient in pizza making. It’s typically made from a combination of crushed or pureed tomatoes, onions, garlic, herbs, and spices. The quality and flavor of the sauce can greatly impact the overall taste and appeal of the pizza. Homemade pizza sauce can be a game-changer for pizza enthusiasts, offering a level of customization and freshness that store-bought sauces often can’t match.
Factors Affecting Pizza Sauce Shelf Life
