I've been wanting to do this, but I've typically had enough cans of olives on hand, to not do this.
I'm resurrecting this draft from March of 2016. I guess if I have not done this by now, do I really need to? We both like olives in our dishes, so I have not found a "need" to dehydrate them for grinding it into a powder.
I guess if you have someone who does not like the texture of olives, but you want the flavor it would come in handy. Same with dehydrated and ground mushrooms.
Do any of you dehydrate and grind up olives for cooking? I'm curious if there are other ideas for using it? Other than adding it in place of diced or whole olives in a recipe?
