Dried herbs will lose their potency quickly if not stored properly. Keep in airtight jars or containers.
After being kept in optimal storage for a year, the herbs will begin to deteriorate.Toss them and purchase new jars.
If you're not sure how long a jar of herbs has been in storage, open up the jar and give it a sniff to make sure they
still have potency.
If there's no significant aroma in the jar, it's certainly not
going to add the flavor that you want during the cooking process.
Store fresh herbs similarly to how you store flowers. Use a
glass or jar with a few inches of cold water, covered with a plastic bag if you choose, and place them in the refrigerator.
