Once you've got the garlic naked, simply place in your dehydrator. If you don't have a dehydrator, you can use the oven. Simply set the oven at 150F and let it go. Just a word of caution here: the garlic will take a long time to dehydrate to the point where you can grind it up. So, if you can't take having the oven tied up for a couple of days, get yourself a dehydrator. You can get some rather inexpensive ones that'll do a great job for this. Additionally, if you share your house with a signicant other, make sure you have their blessing. The aroma will be quite strong throughout the house. This was a battle I knew I would not win (this goes back to my jalapeno and habanero "incident"), so I dehydrated the garlic in the garage. When I post my smoked jalapeno and habanero powder experiment, you'll understand a little better!
That's it for my first blog. Give this a try and you'll like it. It'll give you the feeling that you can do more and when your garlic powder is better than store bought, you'll never go back.
