Fresh picked habby's.....
Sliced and layered on a cookie sheet.
Next into an oven on the lowest setting available or 100 degrees, over night, with the door cracked.
I highly recommend leaving a window open as the fumes are pretty sharp and pungent.
The next morning you can put them in a blender or what we like to use.. an old coffee grinder to make into powder or flakes. Grind longer for powder. Now, here is a bit of advice... Let it sit for 5 or 10 minutes before lifting the lid.
The powder will billow right into your face and you will be sneezing and coughing uncontrollably. Just letting it rest makes this step much more safe.
