There are many options for storing fresh spices, freezing them, drying them and making strong aromatic powders - this is a very good option if you have large quantities of spring onions. But how to keep our fresh spices fresh for a longer time?
Fill a jar or a water glass partially with water and place the stem ends of the herbs in the water in the jar (cut a small part of the herb stems). The spices should be well dried and there should be no moisture on them (if there is any moisture on them, they will go bad much faster, so after you rinse them, leave them onto kitchen paper).
If storing herbs in the refrigerator, cover the top of the jar with a clear plastic bag.
Coriander likes cool temperatures and should be kept in the refrigerator.
Parsley and dill can be stored at room temperature or in the refrigerator. According to Harold McGahey, basil is best stored at room temperature, not in the refrigerator, because it is susceptible to going bad from the cold.
Change the water after a few days and remove the yellow leaves, otherwise the green spices will not be able to retain their properties. Fresh parsley, dill, celery, coriander, basil and other fresh herbs can stay fresh for up to 2 weeks or more when stored this way.
Another option is to arrange the fresh herbs in a single layer onto slightly damp kitchen paper (this way they won't get crushed), roll it up and store it in a plastic container (if you're using a bag there's a chance to crush the spices). Store the bag in the refrigerator.
Store spices by always removing a small portion of the base of the stems and removing any discolored or dried leaves.
Some people store dill and parsley (they shouldn't be wet, if you've rinsed them, let them dry onto kitchen paper before putting them in the jar), by placing them in a dry jar, sealed, which is placed in the refrigerator and this way you increase the time during which it will be fresh.
Store basil by cutting off some of the base of the stems and placing a bowl, vase or jar, with an inch or two of water in the bottom, just like a bouquet of flowers. Store at room temperature in a bright area but out of direct sunlight.
