Homemade vinaigrette is a staple in many kitchens, offering a delicious and healthy alternative to store-bought salad dressings. However, one of the most common concerns among homemade vinaigrette enthusiasts is its shelf life. How long can you keep homemade vinaigrette, and what factors affect its longevity? In this article, we will delve into the world of homemade vinaigrette, exploring its shelf life, storage methods, and tips for extending its freshness.
Understanding the Components of Homemade Vinaigrette
Before we dive into the shelf life of homemade vinaigrette, it’s essential to understand its components. A typical vinaigrette recipe consists of oil, acid (such as vinegar or lemon juice), and seasonings. The ratio of oil to acid can vary, but a common starting point is 3:1 or 4:1 (oil:acid). The type of oil and acid used can significantly impact the shelf life of your homemade vinaigrette.
