Dried Rosemary Sprigs vs Fresh Rosemary Sprigs: The Difference in Texture and Ratio

Fresh rosemary has the best taste, but the volatile oils on the needles that give the herb its distinct aroma remain even when dried.

If a recipe requires fresh rosemary but you only have the dried ones with you, replace every tablespoon of fresh rosemary specified in the recipe with a teaspoon of dried ones.

Remember that dried herbs are at their best for the first six months after opening, but they can be stored for years.

Dried Rosemary will continue to emit flavor if it already emits an aroma. Until substituting, test a small amount to see whether you need to change for potency.

The Right Way to Store Dried Rosemary Sprigs

To save time, strip all of your rosemary onto non-stick tray liners or a tea towel. Tea towels are usually smoother than terry kitchen towels, so needles don’t get stuck as easily.

In a mason jar, vacuum seal your rosemary. You can use a standard vacuum sealing machine or a portable version, but the smaller version needs a little more effort because there is a lot of air in a jar like this.

You may store your rosemary in an airtight jar, but removing the air is recommended for longer-term storage.

If you have oxygen absorbers on hand, you can use one to achieve the same result as a vacuum sealer in around twenty-four hours.

Our Take on Which Method is Best

Dry your fresh Rosemary sprigs under the sun as it’s the best way if you reside in a tropical area where there’s abundance of sunlight.

You can bunch hang them as this is quite common and doesn’t need any appliances for providing you with the same results.

Dry Rosemary in a food dehydrator, oven or a microwave if you require dried Rosemary leaves in enormous quantities. These are also amongst the speediest alternatives available.

However, make sure you keep a constant watch when using these appliances to ensure you don’t overheat your delicate Rosemary sprigs and burn them.

FAQs

While fresh Rosemary sprigs will last 10 to 14 days in the refrigerator, dried and ground Rosemary will last for about one to three years.

When dry, removing dried needles from stems is quite easy. There are no oils on your fingertips as there are when you strip the fresh twigs.

And if you gather several sprigs together and twist them, most of the needles will fall off.

What methods should I consider for drying Rosemary leaves in bulk?

You can use an oven or go for a food dehydrator with numerous trays. Sun-drying fresh Rosemary sprigs or hanging them in bunches to dry in bulk is also a great alternative.
