Fresh herbs will last for longer if stored properly in your refrigerator. The best way to keep fresh herbs is to store them upright in a glass with a small amount of water. With a sharp knife, trim the ends, insert in water, and cover loosely with a plastic bag to prevent wilting. Fresh herbs can also be stored in a plastic bag in your refrigerator.
Most herbs are best used fresh for the brightest flavor, but many can be dried successfully for winter time use.
To dry herbs, gather into a small bundle and tie at base with a long string. Hang upside down in a warm, airy place until completely dry. If you don’t have a cool, dark place to dry herbs, dry herbs in a paper bag in a cool place. Once dried, gently strip the leaves and store in a glass jar. Dried herbs will last up to 6 months if stored in a well sealed jar away from direct heat and sunlight. Dried herbs can be more intensely flavored than fresh so if you are substituting dry from fresh herbs, use a 1 to 3 ratio (1 teaspoon of dried for 1 tablespoon of fresh). Dried herbs can also be used for winter teas.
