I've found dried okra at a store in Annapolis, Maryland. The store is called Fresh Market. They were very good. Even my husband, who doesn't even like vegetables, ate most of them.
I had dehydrated okra as snack food in Japan and LOVED it. This is how I ended up in this blog right now. It is light and crispy and really unique. Nothing like the fresh, frozen, or common cooked okra most of us are used to.
