I was out gathering some wild edibles the other day and I thought i would show a picture of the Pollen I gathered from the male flowers. The Male flowers and female flowers are on the same stem. The male is at the top.
The best method is to cut the flower off the stalk and leave for a few hours to a day then shake in a bag. This seems to yeild the best amount but is very destructive obviously. I usually just bend the stalk into a bag and tap with a stick.
This pollen is like flour in many ways and can be used as such as thickener etc. It tastes very bland but is not unpleasant.
Pollen has usefull amount of protein as well as many vitamins and minerals.
