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.
