What I have found to be one of my favorite items in my kitchen is my dehydrator. I use it for many things.
Drying herbs is amazingly easy with a dehydrator and it makes me feel good knowing I'm not wasting any herbs that I can't use fresh because of the sheer volume of growth. I mean there's only so much sage one household can use in a few months of cooking!
To dehydrate your herbs you will need to pick the herb you wish to dry first thing in the morning after the dew has evaporated or on an overcast but dry day. Wash the leaves to get any dirt or bugs off. Shake off the access water and place stem, leaves or flowers into the dehydrator trays making sure there is plenty of airspace. This batch I recently did was for wild mint. I will use it in teas through the winter as well as in my Tub & Sink Cleaning Powder.
My dehydrator was an Anniversary Gift from my hubby. I asked for it! He bought me a stand mixer another year. He found the dehydrator at Canadian Tire and invested about $70 for the unit. You can buy $300-$900 units but for what I do, the $70 one has worked out just fine. So try drying herbs....you'll enjoy the simple process and the results of your summer bounty in the winter.
