What is spring onions?

Spring onions, also known as scallions or salad onions, are a vegetable that belongs to the Allium family, which includes onions, garlic, shallots, and leeks. They are typically harvested and consumed while still young and immature, before the bulb swells and they produce seeds.

Here are some key characteristics of spring onions:

1. Appearance: Spring onions consist of a long, slender, cylindrical green stalk with a small white bulb at the base. The stalk is made up of multiple hollow tubes, while the bulb is where the roots develop.

2. Taste and Aroma: Spring onions have a mild, slightly pungent flavor that is not as sharp or overpowering as mature onions. They have a subtle sweetness with a hint of oniony essence.

3. Culinary Uses: Spring onions are versatile ingredients used in various cuisines worldwide. They can be consumed both raw and cooked. Commonly, the white bulb and light green parts are used for cooking, while the dark green parts are often used as garnish or added towards the end of cooking to retain their fresh flavor and color.

4. Nutritional Value: Spring onions are nutritious and packed with essential vitamins and minerals. They are rich in vitamins A, C, and K, as well as dietary minerals like potassium, iron, and magnesium. Additionally, they contain low amounts of calories, making them a healthful addition to many dishes.

5. Storage: Spring onions can be stored in the refrigerator for a few days. To extend their freshness, it's best to keep them unwashed and dry. Spring onions can also be kept in a jar of water, like celery, to stay crisp and fresh.
