I have eaten puff ball mushrooms before but I never really figured out a good way to cook them. The puff ball caviar sounds good. I am also intrigued by the pine pollen. I never thought about using it as a food but it is often abundant around here.
Since you are interested in iron chef and are very creative you may also enjoy my Prepper Cook-off Challenge. I am coming out with a new one later today so you may want to check it out.
