Description

Storage onions are a specific type of onion variety known for their long shelf life and suitability for extended storage. Here’s some key information about storage onions:

1. Variety: Storage onions are typically a type of yellow onion, though they can also be white or red onions. Yellow onions are the most common choice for storage due to their durability.
2. Size and Appearance: They are usually medium to large-sized onions with a round shape. The outer skin of storage onions is papery and brown, which helps protect the inner layers from moisture and light.
3. Flavor: Storage onions have a strong, pungent flavor when raw. However, their flavor mellows and sweetens when cooked, making them a versatile choice for various dishes.
4. Storage Qualities: The name “storage onion” comes from their ability to be stored for an extended period without sprouting or spoiling. When stored properly in a cool, dry, and well-ventilated place, they can last several months, even up to a year.
5. Common Uses: Storage onions are often used as a staple ingredient in cooking. They are great for sautéing, caramelizing, and adding depth of flavor to soups, stews, sauces, and many other dishes. They are also commonly used in salads and sandwiches when sliced thinly.
6. Harvest Time: Storage onions are typically harvested in late summer or early fall when their green tops have dried and fallen over. This signals that the onions are mature and ready for storage.
7. Curing: After harvest, storage onions are usually cured by allowing them to dry in a well-ventilated area for a few weeks. This process helps to toughen the outer skin, which contributes to their long shelf life.
8. Popular Storage Varieties: Some popular varieties of storage onions include ‘Yellow Globe,’ ‘Copra,’ ‘Stuttgarter,’ and ‘Ailsa Craig.’

When using storage onions in your cooking or for extended storage, it’s essential to inspect them regularly for any signs of spoilage, such as mold or sprouting. Remove any affected onions to prevent them from affecting the others.

Remember that while storage onions are excellent for long-term storage, they may not be as mild and sweet as fresh spring onions or sweet onions when used raw. However, they are prized for their durability and ability to add depth and flavor to a wide range of cooked dishes.
