Onions are arguably one of the most indispensable ingredients in the kitchen.
They come in many sizes, shapes and colors, each with their unique uses in cooking.
Being a culinary staple, people tend to buy them in bulk. Unfortunately, they often go soft or start sprouting before you get around to using them.
To avoid waste and save money, people often wonder about the best way to store onions.
This article tells you everything you need to know about how to store onions.
Store Dry Onions In a Cool, Dry, Dark and Well-Ventilated Room
Onions are best stored in a cool, dry, dark and well-ventilated room, such as a pantry, cellar, basement or garage .
This is because they easily absorb moisture. If temperatures or humidity are too high, they may start to sprout or rot .
Storing onions at 40–50°F (4–10°C) is ideal. At these temperatures, they best maintain their characteristics.
It’s also important to ensure proper ventilation to prevent molding and rotting. An open basket, bamboo steamer, mesh bag, netted bag or even pantyhose will do.
Avoid leaving onions in plastic bags, as this may make them spoil quickly due to poor ventilation.
Furthermore, darkness helps them last longer. The lack of sunlight reduces changes in temperature and humidity, two factors that can cause them to go bad faster.
