There are several methods to preserving herbs. The most popular methods being freezing in ice cubes and drying or dehydrating. My preferred method is dehydrating. Dehydrating herbs is very easy. It doesn't require any special equipment and one is not dependent on electricity or a freezer that is in good working order. When using dried or dehydrated herbs, remember to use 1/2 the amount of fresh as the flavors are concentrated when dried.
After the herbs are washed, I remove the excess water by giving them a good spin in my salad spinner. (I've been a mother and wife for more than 30 years so, I've had plenty of time to collect all sorts of nifty kitchen gadgets, like my salad spinner.) If you don't have a salad spinner you can place the herbs in a recycled mesh onion or potato bag and while standing on the back porch give them a good shake.
Once the herbs are completely dry they will easily crumble between your fingers. I like to use recycled herb containers or canning jars for storage. I store my containers of herbs in a cabinet near the prep station in my kitchen. Any excess dried herbs are stored the in canning jars and placed in our food storage pantry located in the cool, dark basement.
Growing and preserving your own herbs is an easy, no sweat way of reducing your grocery bill. As mentioned in my post, Stewardship in the Kitchen: Setting a Realistic Grocery Budget , when priced by the pound, herbs are the most expensive grocery item you will purchase. Since herbs are so easy to grow and preserve, anyone can implement this technique and save money while still eating well. Bon Appetite!
