A Food Dehydrator is one method of drying herbs by using a system of heat ( average temperatures of 130F to 160F) and vented air to draw moisture out of thinly sliced foods, or herbs. For example, in my Italian pack was a carton of baby portabella mushrooms which I don't have any particular plans for now. Slicing them 1/8 inch thin, the dehydrator will extract all the moisture, so I can put them in a zippered food bag to be used at my leisure. The mushroom slices can be easily reconstituted by soaking them in plain water before usage. I also have some red bell peppers and Roma tomatoes; just slice them up, dehydrate them and store them in an air tight jar with olive oil, or simply in an air tight bag. Why buy expensive brands of "sun-dried" tomatoes or peppers when you can make your own? Want to make your own potato or veggie chips? Season the slices before you place them in the dehydrator; no frying, no oils.
Don't want them hanging around the home; another method is to remove the leaves as much from the stem as possible. Lay paper towels on a tray (aluminum or plastic); place the leaves on the paper towels and leave a little room between the leaves. Cover the leaves with another set of paper towels to keep dust and dirt from landing upon them; store the trays in a dry area and the herbs should be dried out from two to three days, depending on their sizes. This also works for celery leaves; you buy that large bunch of celery full of leaves, well don't throw them away. Dry the leaves and you'll have them available to be added to stuffing, rice or pasta recipes.
Herbs with small and abundant leaves, such as Rosemary, can be left to dry on their stems. When completely dried out, you can either shake the leaves off which can be rather messy; or grab the cut end of the stem, hold it firmly with one hand while using fingers from the other hand to gently slide the dried leaves off.
Whatever method you use for drying your herbs, remember to label and date your air tight containers or bags, so you'll know which is which, and when your six month expiration is up.
One more method for storing herbs, but this concerns a non-drying method; freezing. You can take a single herb, or a grouping for a particular need, chop them up fresh and place a good pinch in the bottom of each section of an ice cube tray. Cover the herbs with 1 and 1/2 teaspoons of water and place the trays in the freezer. Once frozen, pop the ice cubes into a freezer safe bag; don't forget to label them, and when you need those herbs for a recipe, they're ready and waiting. Remember to take into account the measurement of water that will be added when you pop those ice cubes in with your other ingredients.
Whichever method you use, or perhaps make use of all of them, you'll be in control of your dried herbal or vegetable stockpile; you'll know where they came from, and what has, or has not, been added.
