Onions are one of the most versatile and widely used ingredients in cooking, making them a staple in many households. Whether you’re a seasoned chef or a beginner in the kitchen, having a supply of onions on hand can be a game-changer. However, onions are also one of the most perishable vegetables, and their shelf life can be limited if not stored properly. In this article, we’ll explore the best practices for stockpiling onions, including how to choose the right varieties, prepare them for storage, and maintain optimal conditions for long-term preservation.
Understanding Onion Varieties and Their Storage Potential
Not all onions are created equal when it comes to storage. Different varieties have distinct characteristics that affect their shelf life, and some are better suited for stockpiling than others. Yellow and white onions tend to be the best keepers, as they have a lower water content and a more robust skin that helps to prevent moisture loss and spoilage.
