Aromatic and flavorful, rosemary is one of the most durable and popular herbs. Unlike many other herbs, rosemary loses little flavor when dried, making it a great choice for drying and storing. It is very easy to dry, so you can always have this aromatic herb at your fingertips and use it in your favorite dishes. Dried rosemary sprigs are also a beautiful and fragrant decoration.

Step 3. Hang the rosemary branches in a cool, dry, well-ventilated place to dry

You can even dry the rosemary outdoors, however, it is recommended that this be done indoors for better flavor and color.

  • Good options for drying rosemary are on your balcony, attic or in a pantry. You can try hanging the rosemary bundles on a clothes hanger if that's more convenient.

Step 4. Turn the rosemary sprigs every day or two to ensure they dry evenly

You'll know it's dry when the rosemary loses its flexibility, both in the stem and in the leaves. This should take about two weeks.

  • It is also possible to spread the sprigs or bunches of rosemary on a flat or slanted window, placing them on cement or wooden blocks, in order to have a greater air circulation.

  • Rosemary can be used widely. It is excellent for seasoning pork, chicken, fish and seafood. Rosemary is astringent, so you can put it in hot water and use it to get a facial steam treatment. Its long-lasting aroma is invigorating, so add a few sprigs of rosemary to the hot tub water for a stimulating shower. Rosemary tea is used to improve mood and circulation, in addition to calming the nerves.
  • If you don't have a food dehydrator or an appropriate drying environment, you can keep the rosemary fresh by freezing it. Wash and shake to remove excess water, or run the dried rosemary twigs in the salad dryer and then freeze them in plastic bags. When completely frozen, remove the leaves from the stems and store them in a canning jar, vacuum-packed, or any other tightly closed container.
