One of the easiest and most popular methods to preserve spring onions is by freezing them. Freezing not only extends their shelf life but also retains much of their flavor and nutritional value. To spring onions, start by washing them thoroughly under cold water to remove any dirt or debris. Next, trim off the roots and any dried or wilted tops.
Once trimmed, there are two ways to freeze spring onions:
1. Chopped: Chop the spring onions into small pieces, from the green tops down to the white bulbs. Place the chopped spring onions in a resealable freezer bag or an airtight container. Before sealing, try to remove as much air as possible to prevent freezer burn. Label the bags or containers with the date and freeze. These frozen spring onions can be added directly to cooked dishes like stir-fries or soups.
2. Whole: Alternatively, you can freeze the spring onions whole. Leave them intact, including the green tops and white bulbs. Simply place the whole spring onions in a resealable freezer bag or wrap them tightly in plastic wrap. Label the bags or wrap with the date and freeze. When needed, take out the required amount, thaw, chop, and use in your recipes.
Another method to preserve spring onions is by drying them. Drying removes the moisture from the onions, hindering bacterial growth and extending their shelf life. To dry spring onions, wash them thoroughly and pat them dry with a clean kitchen towel. Remove the roots and any wilted tops. Slice the onions into even-sized rings or thin strips. You can either air-dry the onions or use a dehydrator.
To air-dry the spring onions, tie them together in small bundles and hang them upside down in a well-ventilated area away from direct sunlight. Make sure there is enough space between the bundles for airflow. Allow the onions to dry completely, which can take anywhere from one to three weeks, depending on the humidity levels. Once dry, store the onions in airtight containers in a cool, dark place.
If you prefer using a dehydrator, spread the sliced onions on the trays in a single layer. Set the dehydrator between 110°F to 135°F (43°C to 57°C) and let the onions dry for around six to eight hours, or until they are completely dry and brittle. Once dried, store them in airtight containers in a cool, dark place.
Spring onions can also be preserved by pickling them. Pickling not only extends their shelf life but also enhances their flavor. To pickle spring onions, first, wash and trim them as mentioned earlier. In a small pot, combine equal parts water and vinegar, along with some salt, sugar, and desired spices like garlic or chili flakes. Bring the mixture to a boil.
Meanwhile, pack the cleaned spring onions into sterilized glass jars and pour the hot pickling liquid over the onions, ensuring they are completely submerged. Let the jars cool before sealing them with sterilized lids. Refrigerate the pickled onions for at least a week before enjoying them. Pickled spring onions can add a delightful tang to sandwiches, salads, or as a condiment alongside grilled meats.
In conclusion, preserving spring onions is a fantastic way to ensure you can enjoy their distinct flavor and versatility for an extended period. Whether frozen, dried, or pickled, these preservation methods will allow you to savor the fresh taste and vibrant color of spring onions long after their season has ended. So, give these methods a try, and let the delicious essence of spring onions enhance your culinary creations throughout the year.
