Drying Your Herbs

I've chatted on this subject before, but I find that it helps to repeat this as new folks who have never worked with herbs may not realize how simple it is to dry herbs for winter use.

Ways to dry:

1. Hang Drying – this is ideal for any long-stemmed herbs, tarragon, lavender, sage, rosemary, mints, lemon balm, etc.

Take stems and bundle together, tying them or holding them with a rubber band.  Depending on the size of the stem 10 to 12 stems is a good size bundle.  Choose a hanging location that has good air circulation, minimal light, especially sunlight, and dust.  In my first home I suspended a rack from the ceiling in the basement, draped a white bed sheet over the top to collect the dust and had plenty of air circulation under and around the herbs.  The average drying time is 1 to 2 weeks.  In humid places, like Illinois, running a dehumidifier during the muggy months can help.

Once they are dry, and you know they are completely dry when they crumble in your hand, you can crumble them into jars for long-term storage.  Or you can leave them on the stem for longer storage by placing them stem and all in a zip lock bag.  Herbs left on the stem will keep their flavor several months longer than those crumbled and a year longer than those ground or powdered.

2. Screen drying – smaller leaf or stem herbs, flowers and other petite plants are perfect for screen drying.

Place herbs on a window screen.  You can also use cheese cloth stretched over a frame or even lay them out on paper towel on corrugated cardboard.  What you want is good air circulation again and minimal sunlight.  The herbs will dry in a week or less, but you may need to turn them over depending on your air conditions. 

I purchased scratch and dent window screens from a build supply store all the same size and shape.  For this we then crafted a frame where the screens could slide in and out to make access easier once during loading and unloading.

3. Oven drying – can be used for any herbs, but is best for those that do not do well with longer methods, especially Basil.  You do have to be careful with sage that has a very volatile oil.

Remove the fresh leaves from the stalk and place them on an oven tray.  You can layer the tray with parchment to make it easy to remove.  There are two ways to use the oven, the short method and the long method.  The short method you place the tray in a warm oven (350 to 400 degrees) for only 5 to 9 minutes until the herbs are dry and brittle.  Do not walk away and leave them or you can end up with scorched herbs.  If you have picked the herbs previously (up to 24 hours ahead) you can reduce the oven temp to 250 to 300 degrees. 

The long method is easier because you can set it and forget it.  With the long method you set the over to 350 degrees and allow it to pre-heat.  Then take the tray of herbs and set in the oven after you turn it off.  Leaving the oven door open to allow moisture to escape and allow a couple of hours or overnight for the herbs to dry.  If you have a gas oven with a pilot light, you can use this method without turning the oven on.  It may take 6 to 8 hours to dry the herbs this way.

4. Refrigeration method – this is perfect for herbs with small leaves, thyme, rosemary, marjoram, or savory.

Place the small leaved herbs on a plate or a square of cardboard laid with paper towel and place in the refrigerator.  You can also do this with basil leaves but the paper towel is required.  You can also place the herbs inside of a paper bag, fold the tip closed and set them in the back of the refrigerator for a few days.  In both cases check them frequently and stir them around to avoid wilting and ensure even drying.  The drying time varies depending on the herb.  Thyme is much faster, while basil may take more time.  Once they are dry place them in containers.

The down side of this method is you need extra space in refrigerator and you can have flavor transfer.  Strong foods stored in the fridge may flavor the herbs and some foods may pick up the flavor of the herbs. My husband loves when I do this becasue I clean the refrigerator before I place the herbs.
