White sauce, also known as béchamel sauce, is a versatile and delicious condiment used in various dishes, from pasta and pizza to vegetables and meat. However, like any other perishable food item, white sauce has a limited shelf life, especially when stored in the fridge. In this article, we will delve into the world of white sauce storage, exploring the factors that affect its longevity, the risks associated with spoiled sauce, and provide you with practical tips on how to keep your white sauce fresh for a longer period.
Understanding White Sauce Composition and Its Impact on Shelf Life
Before we dive into the storage and safety aspects of white sauce, it’s essential to understand its composition. White sauce is typically made from a combination of butter, flour, milk, and seasonings. The high dairy content in white sauce makes it prone to spoilage, as milk and cream can harbor bacteria and other microorganisms that can cause the sauce to go bad.
